If you want to get faction top you will need some gkits and ranks but still you can do alot of you have good experience and a good team you can also find a faction to join.
Skyblock is a P2W game like 100000%
Prison is a mine game but if you buy ranks keys you will get more advantage therefore you can no life it and get alot of stuff.
Kitpvp is not p2w game at all only the sets like you can start by killing noobs with decent sets and cap koths like it's just use your brain game.
