Its not even worth it, SA to top A (SoM/BotMT) =140 A gems = 4.2kk aa = atleast 85kk adena. For that adena u can nearly buy S grade mage weapon.
There are ofc, ppl were doing here solo not only common raids but also Tezza/baium/QA. Thing is u need warrior party to that, with full support (atleast 7 boxes).
With mage u can only complain about no autoloot, complain about slow and worthless exp and finally make reroll to fighter or at least create destro with support to exp ur necro.
In giran u have NPC next to gk with tokens for Shadow B Grade Sets/weapons.
