I am on console, and I’m a newer, low level (currently 27), entirely F2Player, and while I agree with OP, I must say that GoW can be quite rewarding, even for one that is new to the game.
Briefly, for me, I decided to endeavor in this F2P experience, sans guild and sans PVP, acquiring most of the required resources via Treasure Maps, by way of Tyri.
Been at it for roughly two weeks, and I have a decent deck and resource pool. Included are 300+ Gems, 256 Glory Keys, 45 Gem Keys, 90 Treasure Maps, various Arcane Traitstones and a few Celestials as of this post. This is after I purchased two of the desired armors from the shop.
I did have some garbage drops from chests, but I do have a few nice Epics, like Marilith and Green Seer. Plus, my Bonnie Rose(s) is fully traited and Mythic.
Oh, and I decided to drop the 675 gems for 50 Event Chests, as I really wanted a Kraken. Got five.
Basically, my favorite part of GoW, aside from the epic music and awesome troop art, is the Treasure Map mini game, and doing them has netted me all of the above witout the assistance of a Guild, or even participation in PVP or Arena.
My least favorite part of GoW is the Treasure Map music and the freaking RNG.
Said this compulsive gambler.
Sticking with the game can be rewarding is all, though I do realize that perhaps I am playing it rather unconventionally.
