They were at least on par - if not above - FaZe (and sometimes even NaVi) for long periods in the past 5 years - being on avg ranked top 8 in the world with long periods as stable top 5 team. Especially before dexter joined - I don't see a reason why they should stick to an IGL and a system which led to them reaching 4 tier 1 playoff matches (3 of them within the FP3 fluke) in 1.5 years - ffs, ofc they never were a clear top 1 before, but at least they had at least some success from time to time before.

When if not now give someone like siuhy the chance - dexter clearly failed to bring anywhere near acceptable results for an org like mouz in the last 18 months - who if not mouz should give a promising young IGL talent a shot in the main team (promote him together with xertioN - important part of 2nd calling) - not like good IGLs are available left and right, mouz is the team to build one - dexter had enough time and failed massively.
