I have been a casual dps player upto M+8.
Meaning I use some addons and some WA for M+.
All the stuff people usually buy on the AH to enhance their performance is
something I have left out. No flasks, potions, food, oils, augs etc. Except for enchantments and gems.
9s not a large jump compared to 8, 10s a bigger one but moreso in that it makes the difficulty kf the trash match the bosses as one if them would always lag behind previously due to lacking fort or tyrannical.
