Since the thread is about discussing alternatives to the Elememe, Iâm going to assume you intend to take Wlk3 and some variant between FF and RC.
The problem I see with the proposed Thauma RC build is that it has a lot of downtime in spite of having Rune Caster. Even with RC, the cd between Warlock spells is simply too long. Most of the Warlock spells are big-ticket skills that require some setup and usually come at the tail-end of a rotation. Using Thaum2 + RC is not the best way to argue a case against the use of Elementalist since the Eleâs skills contribute damage within the time-frame during the downtime between Warlock skills.
Should we consider instead Wlk2/SM2 or a Sage variant (something Iâve been contemplating), the rotation problem is more negotiable due to the very liberal cdâs of these classes but does not discredit Elementalist in that these two high rank skills lack any decent AoE clearing abilities outside of Sage. Condensation is nice but has one overheat. In terms of damage it doesnât even outclass Meteorâmade worse by the fact that its only merit in a Shadowmancer build is that itâs a reliable room-clearing skill in a kit built mostly for few targets unlike Elementalists who, Hail nerf besides, retained most of the power associated with it. This latter class actually complements the Wlk/SM class cap since it provides everything the former lacks.
Now, finally, we consider the traditional Elememe with an RC capstone. I would like to end my argument by saying that outside prioritizing Thaum over Ele, there is no real conflict between choosing Elememe and choosing RC since both can exist in the same build and, in fact, complement each other.
