It's more in regardes to the estabilshed classes. Their changes will have huge impacts on the player base until 1.3 is released. But, yes, I think the new classes interactions should have been heavily tested in T4 (at 40+, ... not weak ass level 28) to see how they meld and increase or decrease a factions effectiveness.

if they need to go into a closed beta setting, so be it. But their method and deployment thus far isn't helping their cause.
