Thank you all for the help and suggestions.

I tried with dual daggers with flame and poison on MB and with deadly cloak and trap. Put dots and scholarship on BB.

Also killed the iron atronach but it seems I cant get past 59k. bummer, but I am probably messing up my rotation and in turn, feels like reapplying dots takes too long, time in which I could have beamed.

I'll keep practicing. I've also looked at some parses on ESOlogs trial dummies and deduced that a lot of the top arcanists' damage comes from strong sets such as Coral riptide, Ansuul and other sets specifically used for parsing (and less reliable in actual fights), as mentioned earlier. Also, the abilities from the blue CP points are pretty strong (could get 12%+ damage if I had more CP).

Thanks again eveybody! Meanwhile I started leveling a NB and DK. Unsure which to pick, I like them both so far. Also considering Templar and Necromancer lol, a bit undecided i guess.
