I think upgrading TT All-Stars is the worst use of coins ever

If you're buying cards with coins to sell them for TT coins in order to upgrade certain cards, just don't. You're effectively creating a BND card. Sure you have a 99 , but you can't sell it as though it's a 99. You'd have to down grade it, get whatever TT coins they're going to refund to you and then sell a 92. If you're using TT coins you earned via House Rules, go for it, but converting coins to TT coins is a bad practice.

Most people have millions and don't care. If you aren't MUT rich then obviously dont do this

I mean it’s mid May and the games almost over. 

any new cards you pick up will likely stay in your team through august

I’m on old Gen and they are only cards that get 0 ap lurker so works for me

Acutally the opposite I want all my CB’s to get One Step ahead & bench press for free then that free’s up 11 AP for my D-Line cause I also have all my LineBackers with One Step ahead & avalanche then my safeties get the both deep zone & abilities for free then the rest I spend on my d line for relentless & inside stuff & double or nothing & secure tackler

well worth it then the chem boosts to boost all the stats to 99 its hard not to spend $$ to convert to TT coins
