when stewy was igl for c9, it was pre astralis meta
now back as an igl he hasn't evolved, he still playing with his c9 mindset and its not good enough. Grim might be a good choice but i think TL need a support instead because the TL core can and will do it better than Grim
Let twists go back to an entry with elige behind him and trading. Naf goes to lurking and closing. If they want to keep stew, pickup an igl instead of grim. Stew is an excellent hype man and entry(even if he doesn't get frags he gets alot of space for his team)
An awp is crucial for the meta now as well so unless Naf or stew takes up the awp full time, they should remove Stew for an dedicated awp. Keep the core trio, their and insane core get the supportive elements proper igl and support maybe supportive awp and TL can get back on top.
