Double warbirds should under no circumstance be allowed. Dual javelins is probably just self-gimping, so I'm not too sure about restricting that. I challenge everyone who doubts the necessity of this rule to a 2v2 against me and P Nut, where we will use warbirds, and the challengers use javelins. Edit: I'm not too sure about restricting use of Smart Bomb. To be fair, if a team has too much trouble with it, just getting Wave Disperser will make it somewhat of a joke. String of Pearls however should be disallowed. When used well, it simply disallows any kind of aggressive tactics making the user overly powerful.
