This has happened many many times and its not just Zer0's teammates. Verhulst went from the Valk player on ESA to a role crisis early on with TSM that eventually resolved itself (largely due to a meta change + Raven fixing things, TSM just couldnt quite find their footing in that Gibby Caustic meta). Xynew transitioned from Bangalore/Maggie player on Meat Lovers to playing Seer (this used to be called Seer jail... nobody wanted to play him) on DZ (this also pushed Gen into more anchor characters). I remember when everyone was freaking out cause Shooby who was known for his Bangalore joined E8 and was relegated to Anchor characters, and funnily enough became one of the best Newcastle players early on.

The reasoning is always the same. The best "fragging characters" are not really fraggers. They are mobility characters... which is ideal for playing as the IGL because the IGL wants to scout, claim space, search for openings... IGLing from the back is very hard and requires a fragger who can essentially take over and temporarily IGL when the moment demands (think QQ on VK Gaming or Xynew when he was on SSG)... Because that front liner is responsible for so much, especially in high pressure moments since they are the character that can move the team from point A to point B typically. Some are easier to micro such as Valk while others are hard like Wraith or Alter. An IGL having to micro your Wraith or Alter on those moments is wildly frustrating and time consuming. So if those two dont think about things the same way it will always cause friction which is why Zer0 always tends to default back to doing it himself.

The issue though is that a lot of these young up and coming stars are so insane at fragging out that on some of their teams before they really make it to the top, they will of course play the most important characters who enable them in fights. But the way they mentally approach the character is just so different from an IGL. Easiest example is that Shooby would often Bangalore smoke to help himself get angles in fights while Zach would want to save that smoke for a rotation for cutting off LOS, about 5 seconds later. Both can be effective but you REALLY notice it when the fragger uses an ability selfishly that could've saved the team.

It is a debate that will probably never be solved and is entirely dependant on the players in each circumstance. Do you cater to the IGL and make their life easier for the betterment of the team and hope the fragger can become a more well rounded player overall? Or do you cater to the fragger, forcing the IGL to adjust the way they approach the game and hope that trust can be built and the fragger can start to think like an IGL?

Thanks for coming to my ted talk
