I haven't gotten to play around with the PC version yet as I updated right before going to bed last night, but I'm very excited to farm traitstones and souls at lightspeed.
Re: some of the more complained about changes -
I wholly support the mana cost nerf for famine. It is already one of the strongest, if not THE strongest, mythics, and it didn't make sense that it had such a low mana cost to boot. I don't think the jynx nerf was necessary, but I don't have a Famine and I'll take that as a blessing... for now
The Kerberos nerf is... unfortunate. Yea, I hated the meta also. Going up against 10 Kerberos' per day was boring and frustrating, but it sure as heck wasn't the 100% Warg summon that was the cause of that. Instead, it's now one less reliable summoning troop for purple days (which is tough enough as it is with so many summoner being purple/red). As for devour going down to 40%, I'm not sure that'll make things less frustrating for players, but I'm not a complex stats in my mind kinda guy so I'll just have to see how that works out.
Overall, I'm loving the patch so far, and looking forward to playing on the PC tonight.
Thanks for all your hard work, Devs!
