I'm happy to say that I got my WF levelled up nicely because it happened during the time that IGG was still doing the nice LTT during jewel spend events. I got my first WF from coli then the spend events I solely went for his perfect talents or shards or hero cards... first time I ever went for a new hero... and it was fun for a while then I think IGG noticed lol how many non cash spenders got WF up lol. So it's still sad that it got nerfed haha probably won't try to go for a new hero again
Wolf is the best tank in the game. It is supposed to be hard and nearly impossible to kill, that is quite literally the purpose of Wolf. Learning how to kill things hiding behind the wolf is what you need to do.
