The ability for two groups of players to challenge each other to a specific warzone. Then you could have tournaments / leagues. Remove all rewards (comms, exp, valor etc.) from these matches to prevent exploiting - make it just for fun (or bragging rights).

RE tanks throwing guards on people and running the other way - Sometimes tanks are required elsewhere, eg. to gaurd the non-focus node. Throwing a gaurd on someone gives them a 5% reduction to damage taken even when the tank isn't near, and (for powertechs at least) gives the tank a 5% increase to damage done from the BM set bonus. You can remove an unwanted gaurd by right clicking the gaurded icon if it's causing you a problem.

I have a ball with my Shield Tech. More suited for objective/team focused play style than 1v1 though, i.e. gaurding (node or healer), delaying enemy reinforcements and to some extent being able to move defenders off a node to let team mates cap. They're great fun in hutt ball too.

I think it would be a good idea if there was some mechanism by which one team/guild could challenge another team/guild to a specific warzone type match. This would enable things like Hutball leagues to be set up and allow teams to play more evenly matched and challenging warzones. This would be more effective if there were more interaction between the factions, such as a neutral PvP-centric space station (possibly in Hutt space) where both factions shared a general chat channel. It may also help reduce the sense of emptiness on some lower population servers. Any suggestions or comments?
