Agreed the timing is terrible,
but what I heard from ''trust me bro'' source is that, his calling isnt that good, that its more the work of their coach twista.
In FaZe yes they suck but north still didnt suck, even after they swap IGL, BIG is in similar situation but people just dont care because they have been irrelevant.
In ENCE its confirmed that there were some internal issues already before, so fixing them makes sense. And if it's true that strats are mostly done by twista I dont see a reason why ENCE couldnt still succeed under new IGL.
It might take a while but its certainly possible. And while it's not all about firepower it plays a big part and ENCE had probably the lowest fire power of top teams and one of the best strats.
The structure is still there, they have played under it, so it still could be there after the swap.
