What link says is actually what I mean. It's kinda frustrating when you can't hit someone because he's tomporily invincible. Ofcourse I understand it's part of the game.

You should understand I don't hate shields. In battles with more than one players and not in one of the official levels they're sometimes (not always) fun. Not in duels, like yesterday in yer new CTF level, because it's kinda unfair, especially in small levels.
