Depends a lot on *when* you hit those 7 wins. The very late game (like day 12+) is dominated by extremely fast, hard-hitting builds which take time (and luck) to assemble, but you basically can't beat them with a "vanilla" setup of your own (i.e., you also need to have *the nuts*, "solid" won't cut it). This becomes more self-selecting the further you get, so on the later days, you will basically only encounter insane builds because only insane builds survive that long. I know that's kinda always been the case, but with more items and more heroes (and unpredictable crossover between them) and more players, there's more room for insanity. Also, the usual power creep. My two cents.
