What do I do with... (in General)

To the old pros, been a long while since I grinded out as many turns as I have recently but...

My main, front line tank has 105K xp to blow, and I don't know on what. I don't remember any of the rules :( Does GA stack with another GA? Should I do just stats? Should I do more ablative shield and be a hp machine and does ablative stack? Is VA/Blood worth doing? Tried archery, not impressed, did etherial chains, sucks poop with my Dispel so high...

What do i do? :(

train some more strength and dex on the tank

if you plan on keeping that CoBF on the tank dont train anything but the main stats
