Hi GMs, I have tried hs myself when I am training alone, however I noticed that there is no increase in exp earned when I hs and without hs myself. I have asked one of my guildmates, they said that when they solo party and hs themselves they will get some hs exp. Please kindly help me with this issue. My hs lv now is lv 16. Attached is the screenshot for the exp with and without hs.
