The elites will tell you three things:
1. Be happy in the lower levels
2. Be happy to lose to their credit card teams on a daily basis
3. Play live tournaments if you don't like combinators
They will stop short of telling you to quit if you don't like it, because they need jobbers to beat on.
I didn't accept that, so I walked away despite having been in the top 20 in diamond tournament standings the past 2-3 months (most of those spent without winning a single tournament until the day I actually quit). For what it's worth, I had a few combis but I tried to pad the squad out with the best non-combi players I could get my hands on. Resulted in alot of pity pack finishes/silver choice packs with the occasional gold/low diamond choice. All in all, 2+ months of being nothing more than a PTCS points compiler with nothing to show for it. That took me to the end of my rope pretty quickly.
375k just isn't enough to build a top flight tournament team even if you get absurdly lucky. That probably only gets you 1, *maybe* 2 of the meta combis. Then you have to consider fodder to give them. The math doesn't math at that price
Being just another loser isn't my idea of fun, especially when I know that if you give me an even-ish playing field I can probably win at least one major tournament, maybe two.
