My squad the 613th was created as a Knight squadron and will stay that way. If the ENY is too bad, or the arena is full, we change to a different arena, not usually a problem.
I have no problem with squads or individuals that do switch if it's done with class.
One day I was attacking a Vbase with someone. He was bring troops, I was holding down the uppers.
He died, I died, I returned only to be killed by the very guy who was assisting me. That was a no class move, by a player that is know for that type of play.
The AK's switch every tour. No matter their chess piece they play with honor and always bring a good fight. I wish they would stay nit though, I can't seem to best Dogg EVER!!!!
When it comes to ENY, I usually fly high ENY planes, so rarely am I restricted. When it gets over 20 or so, I usually do a buff run or something else since it often resolves itself after a little while.
