It's too simple. With that logic, if you didn't like some combat animation, you shouldn't fight at all?
In a CRPG, atmosphere matters a lot for many people, and in my eyes, doing somersaults with plate armour and a two-hander strapped on your back can kill the atmosphere. Yes, there is magic in the world of Rivellon, but the somersaults apparently don't require or consume any magical energy. Since I haven't played the game yet, I can't tell for sure - however, it might feel like you're not playing a hero anymore, but a super-hero without a cape who is out of place in this fantasy world.
I'd like to switch off the somersaults if that's possible. But if it's not, I wouldn't want to run around for minutes to avoid a somersault jump, either.
It's a magical fantasy world in a video game for crying out loud. You know, a world where you can experience things that simply are not possible in real life? Are you really going to nit pick about armor being to heavy to jump in because it goes against the laws of physics in real life? Maybe it is just me, but something so trivial certainly is not going to take away from my immersion in this grand world they have obviously worked so hard to bring to us. I suppose to each their own, though.
