Not sure if you are aware but you can game the system quite effectively. Put a 220 in grp with mostly people 20 level above the boss and max sharpen weapons. Buff outside with poison weapon. Max out the low level(s) with gear no noob could ever hope for. Making a level 80 takes at most a day or two if you try.Or a level 60 could walk in and hit it twice and lock itA higher lvl would just come by and snatch the boss, like lvl 60 event bosses.I hope the noobs get their own version of a raid boss like aggy, hrung etc. Th gear options for noobs is super limited and not very good. Like regen braces, crummy otherworld skill rings, no charms, heroic rejuv? Getting 1-100 should be fairly quick and the player should experience many upgrades etc. Nobody wants to come into a game and see that their only options are buying plat or farming and merching for hours upon hours for weeks to get basic gear. That's how you'll keep new players playing.
New players are locked out of same level content all the time, it's possible to use target lock for the opposite of intentions.
