Floaty? That's really odd. GW2 characters hop around as they walk, so, if anything it should feel more grounded.
I also don't get how the animations in wow are unresponsive when they clip over each other. Did you play melee? That might've been it. Before legion the auto attack animations and the animations for some strkes looked very "samey". It's not like that anymore. WoD revamped the models and Legion revamped the animations. You should try it again. It is very responsive.
On topic, i loved GW1, but GW2 felt so much less to me in the combat system. I imagine it got better, but i don't think the new trinity they wanted to make could or has worked. Taking out monks was a huge mistake. Basically i think GW2 tried too hard to re-invent the wheel they had already re-invented with GW1, but it didn't quite work. I always felt like Guild Wars was my home in MMO's and it got robbed of me by GW2.
I really miss it and i wish they would make a GW3 that was what they originally said GW2 was gonna be: a GW1 in a persistant world. So, i'm not surprised GW2 is dieing a slow death unlike GW1, wich they killed. Karma i guess...
