Multi team dom would be a nightmare, with flags just constantly being capped, and taken back and forth. I wish they'd get rid of multi-team hardpoint, but that is their new game so they probably want to ram it down our throats- HP is the worst game type ever. Multi team is much more fun when it is TD or KC.
Multi team was a good idea, but like Face-Off, I think it needs its own maps designed for 3v3v3. I didn't think i'd like face off but I loved it, and i was really excited for multi-team, but am disappointed, especially when hardpoint comes up.
