Boasters genius igl strats are literally just “derke carry us”
I disagree, take fracture for example, Fnatic has some strong strats on that map as seen when they faced off against C9. I think the reason why many people think that Derke carries Fnatic is because of his sheer impact, in the game against C9 on Fracture Derke was entrying and almost always being good for atleast one. This takes attention away from the supporting utility which enabled Derke to actually do that.
However, I would say that Boaster's strats don't work as consistently without Derke. Again, because of Derke consisitency and impact, Boaster and the rest of the teams jobs become a lot easier.
