What subskills are actually good? I've leveled up a few subjobs and nothing I use seems worthwhile.
On my PUG, I tried Bloodbath out, which was healing for 25-35 HP with a cooldown around 1:45 (compared to over 100 HP and 1 minute cooldown on Second Wind). I tried to use Ferocity in conjunction with it to get more damage and a bigger heal, but that didn't really do much either. With the huge stamina cost of combining those two abilities it was -very- underwhelming.
Having a lengthened cooldown as well as a reduced effect seems overkill to me.
I think I'm going to get Gladiators defense boost and Lancer's haste next to see if they're worthwhile.
Have you guys been able to come up with nice builds using subskills or have you found any diamonds in the rough that are really effective?
