I think people are missing the boat here. unless you have spent a lot of money, your best bet is to continue to build a balanced roster. especially until you see who the new character is. Why???
The "events" system is being completely overhauled. The Jedi event will go away and then come back after a couple of weeks. what is happening in the event section in the meantime? another restrictive type of event! (ie: nightsisters, sith, ewoks, resistance, First Order)
First of all, i really hope this is what happens because it sounds awesome! second, it's genius by CG/EA because those without self control will constantly be chasing the next reward or character.
So if you are F2P or a light spender maybe slightly alter who you get with shipments and such, but keep in mind my theory because it could impact your long term success and your ability to keep getting those shipments in GW and Arena because of some of the F2P Jedi not being quite up to snuff.
Curious to see other's thoughts on this
