Whoever asked about what 2H abilities are worth it... dunno, all of em? Kinda depends if you have FF on or not. I've run across a few things now that has me re-thinking my builds. Not my warrior/reaver build though but I only used the counter in 2H tree anyway so... yeah. Counter can't block heavy stuff. It can block an auto-attack from the 2H maul guys, but it wont stun them or cause them to flinch, so you'll often get hit by there 2nd hit anyway. Still, with enough hp/guard the original counter could net you enough to absorb the 2nd hit and counter the third.
My main advice, for anyone doing a 2H warrior - especially in Nightmare like me... get Counter, and get the dodge roll. That combination can keep you alive about as good as Shield Wall. Course, Shield Walls just universally better but it beats getting pummelled to death. Also the guard bonus from block is, maybe, misleading. It says 15% guard, but I've gained more then that before... think it varied depending on what you block.
Anyway some other awkward bits (and semi-good news). Static Cage is FF-friendly... Chain Lightning, for some reason isn't. It will chain to your party, and it will screw you over. More so then that you have no real way to control it. Unlike Immolate, or Winter's Grasp it's not a directed AoE. It's not 'where you point' or just around your target - it's all over the goddamn place. You upgrade it and you will hit your ENTIRE party rather consistently. A lot of stuff in this game feels designed around having FF off. MP has no option for it being on, and even if you turn FF on the enemies aren't subject to it. Only enemies that are hostile to each other will hurt each other.
FF feels like an absurd handicap for no other reason then to handicap your self. It's not the survivaly/believeable toggle I was originally hoping for. I mean you basically kill a bunch of builds in the game, and make a bunch of skills just blindly useless.
So you know, lesson of the day, if your gonna play with FF on (which only YOU suffer the negatives of, enemies apparently keep there FF to off) don't use Chain Lightning. If the AI uses it, it'll hit your party. If YOU use it... it'll hit your party. The only way it doesn't hit your party? You fire it far enough away (maxed out that's like 9 meters from the closest possible target to you) and have at 'least' 6 enemies for it to bounce between. Anything less then that and your party is getting zapped.
Static Cage is awesome though... short lived, but awesome.
