sooo titan?

I have the first few phases down, the bombs have sweetspots where I can stand, the problem was, the healer going nuts with medica overhealing during geocrush, it takes provoke to get everything back under control.

The issue isn't during geocrush itself as any whm is going to medica at that stage. If they are using medica 2 right from the offset then you need to step in and suggest they stick with medica 1 at least until after the first geocrush. That'll hopefully give you the enmity headstart you need before the heart phase. If things still aren't working out then either they are ignoring your suggestion or you aren't generating enough enmity.
