i think its obvious that the illum missions will be open again. Which for me is good since i have time now, and not before. I only reached half a rank i think. I want to get that nifty vehicle, and suit. And possibly in this life time, that weapon if there are enough ways to get that helix component.
For pvp, they need to balance it more and then add more to what already exists. I say this because, I believe that they have the maps on random rotation so people learn less to exploit the maps, or form perfect teams for certain maps. Which is why balance should be better considered. Sometimes in pvp, nothing is happening on the oppsing team, since they have heals, shields and a bunch of other unclear reasons for them to take no damage. That feels very unrewarding, and is literally just like pvping on a training dummy that never dies.
So for pvp they can balance, add more map variation, and the ability for us to choose which maps. I still like Huttball the most. I do not feel like playing other maps, and going to some other map randomly really sours the pvp exp.
At this point, they have enough WZ, they just need more maps for the existing ones. Well, I guess they could add more sport WZ's. That would be fun, but I think as far as sports goes, Huttball works well as a WZ. Anything else, and it might as well be a different mode of huttball... for example having to pass the ball every 3 secs as if it were tennis/badminton or other modes are possible.
But what they dont have is large scale battles that can have forts. Or duel areans with tournament modes with gambling... that would be fun for RPing BHs. Or maybe adding something in the open world that is persistent including moving NPCs, certain exclusive resources in certain areas that tie in to a large reward as well. Or a WZ like duel arenas that includes companions. Or a WZ that gives people perfect gear, and there are no differences, and the game scales with achievements in the instance similar to MOBAs or DOTA. I think the last idea would be cool, and maybe making it unique by allowing people to control points on the instance/map that has benefits or NPCs that can be controlled. For example NPCs can have thier path directed in a certain way or told to guard a certain area, to help heroes fall back. Except something like this should be added after the expected pvp content is in, such as large scale battles.
