I would like to see more travel powers added to COH/COVs. There is simply not enough diversity on these power sets.
Some suggestions:
Summoning vehicles: lower levels can be as simple as jet packs or motocycles, higher levels could summon vehcles to be used by a 8 person team.
Super Swimming (considering all of the water in this game, why not?)... related to this, where are the underwater zones??
Wall climbing: (yes, it is spiderman-esk, but if humans can do it now with suction cups, heros should be able to do it as well.)
I am sure that there are more possibilities. Travel powers are necessary, but largely boring and I hope they are added to.
