Should I start doing the collections now or hold off to see if prices drop?
Was hoping to get some insight on that. Are the prices of players right now worth the xp?
How much have you already done?
How many stubs do you have?
Are you a flipper? A grinder? A BR god?
Are you an onliner? i.e. Will you be going for the Prestige versions or are you happy without the red?
Every player is different. Thus every player will have a different answer to your question based upon the other answers.
We can't give you any insight if you don't give us any either.
