Hello there everyone

...im an old Allods player been playing it since it first came out, had alot of fun till the patch when we had the lvl 55 level cap increase, i think it was named "Heart of the world" ....but then i left the game for some reasons here in real life, but i am finally able to play again, but im in need of guidance to some questions :
1- can i still come back and be an effective player again?, noting that im no longer able to pay on the F2P server nor being able to subscribe for the P2P server :/ , yet i can play around 6+ hours per day, so is that enough to become effective again?
2- can someone please give me a full list of patch notes since "heart of the world" or at least the links to each one , i have to read them carefully cuz i have alot of catching up to do
thank you in advance for all those who might help me, and i hope the game still has its amazing and friendly population the way it has always been for years
