May be they don't wanna be the best team in the world right away! Cz often stack rosters don't perform upto expectation, so it's a big financial risk. For teams like SEN, 100T, C9 etc who have a lot of fans that want success, org actually need to feed to the frenzy sometimes and convince the fanbase that they are building a roster ready to win. But for EG, that's not the case. A home grown talent development structure is lot more sustainable and makes a lot of sense for them. 'skill gap' isn't a permanent issue, you can mitigate it with hard work, good coaching, building team chemistry etc.
