Did you read what I posted? lol. if you want max xp and will be using pots.. Also, 200 or less strength is guaranteed slower kills whilst solo'ing.i gotta say that as a warrior which has str as the only dps stat, and much higher melee weps than rogues, str doesnt add as much as u think, not to mention that the more u add in it, the less it'll give u, thats the problem with the str forumla, and it really annoys meI'd class killing fast and staying alive as the best solo build, which is why I'd have more strength than a few people are saying.. Strength rocks for solo as the mobs don't have such high resistances so the skills hit higher.
With 615 stat points I'd go more about 225/225/10/185, adding to all 3 as you go.
Best way to get energy is from lux, a Heroic Ammy for example (star Tali at level 150), or an energy regen brace. Having such low strength will make for slower kills which in turn will make for less xp/min and more regen needed.
Riposte also kicks ass solo'ing, should always be maxed. For those that want max xp from lvling and will be using pots or sigils (so don't need survival skills), the build I use for solo'ing (I use sigils) is:
Strength: 410 (560 with axe, wouldn't recommend that much, but I use DL Rondel most of the time which has 0 stats)
Dexterity: 350
Focus: 10
Vitality: 330
Skills:
Max Sneaky Attack
Max Shadowstrike
Max Quickstrike
Max Riposte
Rest in Rend
You will tear through mobs
also the point that dex is much better soloing stat is surviving, most of best soloing skills are dex based, such as life steal and fast reflexes for rogues, therfore why dex is great for soloing
Strength also adds more than most think, especially whilst levelling. 560 strength allows me to hit up to 8.6k sneaky attacks. It allows me to hit up to 3.2k Quickstrikes and gives me 1.9k damage along with those skills, allowing me to hit up to 1k auto's without lure (granted some damage from gear). If you want good solo xp, you need fast kills as well as survival. It makes for less regen needed and next-to-no down time between kills.
