Needing to join a guild on PC/Mobile that doesn’t require me to join a discord or use chat.Casual but active is probably best, don’t want to play Gems as a job even if I have the time. 
Lv 1200+
I do max seals I can a week. I do all Guild events, usually buying up to t3 or 4 (I’m fine with mandatory guild wars, just know I’m not the greatest.)
Can contribue around 500-600k gold a week, and 250-300ish trophies.
I don’t know if they have any spots open right now, but The Elders would be a perfect guild for you. I was with them for a few months and I can say that they were pretty active with casual requirements. You can message the guild leader here: Profile - Leothwyn - Gems of War | Forums
Tears of the Dragons matches what you’re looking for. You can join without invite, but if you can’t get in, give me a shout.
If you whant you can Join Guild “Herz aus Gold”. We are a german guild at place 1284. We don’t have a must to join discord even if we have one. We are looking for new players which are active to climb further. If you are interessted let me know.
