That I actually use? Nah. I end up just getting used to loadouts that i have for countering, and end up liking them.
One thing that i don't like is when i have to switch to my stealth arc loadout though. I'd prefer to just run around, and do something. But some games call for just waiting around(lobbies filled with pr+specs users, or too many smaws for explosive focus), which makes thing slow and annoying.
