Acry, the sheer amount of misinformation you share in these forums is annoying. I even blocked you, yet you're still able to comment on my post.
"if youre good at placing phalanx you can stack it many many times for alot of damage"
-- Half true. This only applies in a scenario wherein what you're attacking stands still within the Phalanx minion's specific targetable line of sight...if what your attacking doesn't fit that criteria, then it doesn't get hit. This almost never happens in end-game boss fights wherein what you're fighting moves out of the line of sight of your Phalanx minions just as fast as you can cast them. Throughout the span of any given end-game boss encounter, only a small fraction of your Phalanx's total projectiles fired hit their target. Bossing with Phalanx is like role playing as a chicken with it's head cut off. It's god awful.
Phalanx is an ass skill bound to an outdated minion mechanic. It has no place in any actively played & updated ARPG of the current era.
