Why you don't stream?
My pc can't handle
CT or PB?
For high keys you should use CT on pretty much every fortfied key besides Workshop and Bostering/Enrage Siege; if you are playing low keys like 18 under just play PB
Can I do decent damage without 3xSS and 3xEB?
If you only drop one EB yes, you MUST have 3xSS and 2xEB atleast; TTK and HoD are both fine (I actually play 1x TTK in KR, Workshop and Siege)
Why you don't play outlaw?
Sin actually outdps outlaw in many keys; and I don't enjoy outlaw at all
What corruptions should I buy?
Stats are way more important than corruptions for sin, especially crit that is over anything; that being said, you need a mix between severes and strikethroughs
My Final build with maximum corruption resistance (135) will be something like:
r9 Severe: 3x r3s; once you're fully socketed gear you'll be around 61~63% base (you don't need more than that)
r16 Strikethrough: 5x r3s, 1x r1
you can play above 40 but I don't recommend in progression keys, we don't have much to deal with high corruption (like outlaw) without compromissing our gameplay
ps: I tried to only give informations about push weeks (fortfied weeks) most of them don't apply on tyr
If you have any other questions feel free to ask me, but I'm toooo lazy :) I don't have a guide or something like that ready for you, I recommend you to search for Ryfie's tv stream and discord, he does alot for sin community with guides and stuff
