Keep everything the same.
But multiply the xp you get from first time elite completion by the life you are on.
first TR = life 2 = x2
fifth TR = life 6 = x6
And for everyone who has grinded out completionist already, give them an extra +1 of everything before you implement this change. And maybe special color wings too =D
This way everyone gets what they want. People who want to run elites and get a reduced TR grind, they get it. People who want to run Ex9/H/N for xp, or solo normal only, they get what they want, too.
