how is edg and heretics situation different than every other team i mentioned, those two do not have the most success out of every team there. but to anwser your question it does and doesnt make sense to run it back, sure each team was insane this year and had good showing but looks at the facts, there has never been a team that did good back to back years and still did great by keeping the same 5 players and coach. (besides maybe prx and fnatic if you count getting grouped and 0-2 at playoffs a good year) it cannot hurt to change.
loud 2022 win champs -pancada,sacy
get 2nd lock in, win regional, 3rd at champ
fpx 2022 win reyk - ardiis
4th at lock in, make both internationals but get shit groups
optic/nrg - yay, marved
5th lock in, 4th tokyo
you can say that it make sense to run it back but historically it really doesnt.
