I've played many TI/MD and IR/MD players. Coincidentally I haven't lost to any of them yet. Infact last week I played the #5 guy in WT twice, and he used TI/MD. I beat him both times, using my allrounder.
The only reason why I've beaten them is because I played better, not because they are balanced now. TI/MD and IR/MD are still too strong.
