This should clear things up Napol.
At level 80 your fighting eyes. Conceal does not work on eyes. Once you get to trees, horses, and rock guys you will need it. Higher level groups also ask for it so they can get to tight areas or just to make boss fights easier. I felt the same way you did - conceal sucks - until i got past eyes and into trees. Try running to the second otherworld laystone without getting hit
Next is rapid shot. If your doing DEX then rapid shot does not matter, and you should keep it at 1. If your doing DPS then increase rapid shot so that you can bolas, run away to max targeting distance, and cast rapid. Have enough points in rapid shot so that rapid runs out right when the mob gets to hitting distance. Bolas and repeat for hard mobs, or tank the rest. With a quartz bow you should be able to tank the rest with not much trouble. When you get to the eyes that freeze you, save rapid shot until they cast icy glaze. Rapid shot above a certain level will cancel out the freeze spell ( a life saver). Now for a knuckle build, you want rapid shot at max so that you get the max benefit since you must switch gear during battle. Also note that depending on WHEN you cast rapid shot, you lose 1 shot at the start of the spell and 1 shot at the end. So at level 1 you don't really get as much benefit. And you wanna talk about haste gloves, I have 30% haste gloves and rapid shot is still way faster.
Next, if your telling me bolas is only good at boss fights, i am wondering where your soloing. MAYBE at stone vale bolas is not needed, but trust me if you wanna solo and not group train you better have bolas. Its like having the mob at 1/2 life by the time they reach you. If it wasn't for bolas i would not be able to train solo at all in otherworld. Well maybe with a ton of pots. And if you light heal the entire fight its very inefficient soloing, and at higher levels with horses and trees it won't work.
Defensive spikes. Yay, defensive spikes. It looks really cool. It doesn't help much and is a waste of points. Well i should say it could help if you have the right group, but solo its worthless. Remember, I'm trying to help Alesta solo.
plus 13 per tick is alright for meditation, but i would recommend you buy a rejuv ring for 25k and lux shop in otherworld. Plus 5 all the time is as good as plus 13 after you cast meditation. And most people can spend the 25k. This would allow more points for other things.
I might just try not to get hit once without using conceal. would be an interesting challenge. I can make it all the way into lava fields with about 7 light heals en totale. This includes golems in very inconvenient spots. The dominator is easy to get to though, rockalanche is harder by a bit and a half. Deepcaller is easy to get to for me personally. I might try going around the wyverns more in lava fields, I might just be able to get to aggy without conceal... that would be sooooo cool. I dont use idols pretty much, so I have to depend on me avoiding attacks by mobs more often than most CH players.
For rapid I prefer to not use it as I have haste gloves and it works more effiecently than rapid. Example is go to the one corner in farcrag. With your bow try to shoot and kill all 3 dummys before any respawn. (U being dps this might not work as well but when I did it with about 100+ in strength I couldnt). With the gloves and no rapid, U cn kill all the dummys and wait around a bit before the first one respawns. I personally would recommend rapid at 1, and use until one has heroic haste gloves.
For where I train yea ur right I train on stupid eye balls.

But I can get to pretty much any tree without help from others (havent tried oaks yet but I'd just ley to tower then go through golems as its waaaay easier.) For energy, if I have 20 per tick I never run out of energy, which means I can light heal and sharp and steady aim and spikes all day.

I have fought against the lvl 100 trees in a grp, sometimes as the tank. I prefer this as I norm team up with a mage or two, and I can keep up with those trees with my light heal. A quick question: how much health do you have, being dps? When I say I tank through something I literally mean tank it. 1.1k+ hp and a 321 light heal (342 with golden quiv of ice), adds a fair bit to my health. I do around 100-150ish dmg per hit on an eye with my bow atm (again more dmg with ice quiv). Atm I have killed bolas, and I do not plan on putting any pts in it until my four skills that I use are maxed.
On to poor Defensive spikes.

They are very useful to me as a dex ranger, and have increased my dmg per hit to 100+ every time I cast it. I find it very useful.
Yes, I use those rings. I was saying that if one wants to gogogogogo, keep a bunch in meditation as it will help you immensely. Without many pts in med you will spend more time sitting around if you have a full health bar and little energy- which can be very frustrating to all in a grp, or even while soloing. Once one gets enough energy regen that they do not run out, kill med. period, as one doesnt need it any more.
I use knuckles so I have rapid at max, but without a rejuv its hard to put points in it.
maybe I'm going crazy but when I cast rapid half the time I lose a shot. It shows the shot but it does no damage.
Without rejuv... this is one of the main reasons I dont like rapid that much, it costs energy, and alot when its maxed.
this 'losing a shot' happens every time to me.

I just thought that it was normal?
