keyes worth it?

So far I enjoy Keyes because it is more exciting combat-wise.

BAFs are just three rounds of tank-and-spank vs the AVs with a few people fighting the adds.
Lamda is a bit of early steamrolling, then running around like idiots while 2 or 3 people take out the containers/boxes and leave all the enemies alive, then a tank-and-spank.

But Keyes, everyone is actually fighting nearly the whole time. And you break up into smaller groups often enough that it's not one attack per spawn before everything is dead, like a steamroll team, there are usually plenty of chances for 2 or 3 people to take on big groups of warworks. I like that much more.

That said, I think the reliance on healing is the absolute worst decision the Devs have made in years. We need more mechanics that convince people to not choose heal sets. They are in all other parts of the game the weakest form of survival, but because some other popular fantasy MMO is built around healing there is a false belief they are the best. The Devs stepping up and making heals the only thing that works is exactly what we didn't need right before a bajillion morons join the game in free mode.
