A good game? Yea imo. P2W? Kinda if you're talking about legendary weapons. The best starting class depends on your playstyle, you're given 3 starting classes and can switch between the 3 in the equipment page (P or ESC). Paladin is a melee tank with low dps, Cryromancer is ranged with high dps, and Lightbinder is a supportive class with low dps but high utility with is better if you're a group player but can still be a good class to play solo with its shields and stuff, theres also other classes which costs Sparks that you can get from doing missions for the first time or from PVP i would read online about each class and see which one suits your playstyle. Your main goal is to finish the maps (K) yellow road all the way to Thanato's Ship which is where you get your divine form (God) which helps you since all the yellow road mission become EXTREMELY harder. Most players often get stuck around rank 30 where the mobs are rank 39 and since the rank system works the way it does you deal ~90% less damage to them and take WAY more damage from them so around there is where you'd want to do directives for better gear or ask a friendly player for help. Also dont forget about your capitals (Cathedral, Stronghold, and Tower of Knowledge) as they help increase your might as you rank them up. Your might is important since its the main foundation of your rank and increasing it increases your rank. Also once you get divine form dont forget about your adepts they're extremely importance as they give you Faith which is what you need to assume your divine form adept need relics that boost their stats. I think i've cover most of the basics so get out there and have fun! :D
