I'm not arguing that Enlarge doesn't make some options really choice just that there are a lot of feats that make Warlocks really choice at this point.

For a DC caster that is not going to take Maximize/Empower it's a fairly easy call but I think for anybody else it is on the bubble or off the edge. This would be my reasoning on why:

Maximize, Empower - no brainers to up either ES blast/burst, SE Consume/Stricken, BBlood, EWave, TS Stun Blast, EBall, generally some combo of the lower level stuff and a finisher that get cast fairly often in rotation.

Quicken - Speeds almost everything up and while some builds can avoid it most shouldn't, especially if they're going to be taking AE damage a lot.

SF: Evo - to max pact damage hitting. Less important for some builds but important for ES builds.

SF: Nec - Important for the non ES builds for the most part for the Magister twist. Some builds will take both.

Spell Pen - Important for all builds for the twist. Even ES builds can use it for Disco Ball and Otto's Irresistible which has a spell res check.

Force of Personality - Important for everybody, although some people will figure out ways to not take it.

That's 6 feats, assuming just one of Evo/Nec, before Enlarge really comes into the picture for most builds.

The competing feats at that point include Insightful Reflexes, SF: Enc, Heighten, SF: Transmute (Flesh to Stone), etc.

Would you recommend people taking Enlarge in general or just in Reaper for the safety and distance it provides?
