Ever since I learned of Homecoming, rushed to relive all the stuff I was yearning for when the game was live, then finally got into the Incarnate stuff, my outlook on the various ATs has changed somewhat; I found that liked the Sentinels' single-target focus early on, but their damage and AoE capability quickly became concerns. I've also moved more toward ATs that can provide some benefit to the team, besides just damage, damage, and more damage. I do like how 2 Sentinel APPs offer heals, but besides that, they neither have the damage to quickly wipe out swathes of enemies, nor the durability to tank, (speaking generally here, not in terms of high-performing instances). They are, though, a fun soloist, and fulfill an itch for that armored ranged attacker...
