U cant be serious. Now the trend is to make all past ranks useless as they implement new ones. So u telling me Ele 3 will fall off when rank 8,9 and 10 are released LOL. What i truly believe is ur thoughts are too linear imo. Every single class u get matters in some extension, and Ele 3 is the MOST consistent build for damage right now, and i cant see a generic Sorc 2 build outDPSing an Ele 3, not by far. Summon damage scales terribly as the max level is 10 for ur cards and 1.3xINT is nothing compared to multi-hits spells like frost cloud + quickcast.
People say all the time sorc damage starts to get really bad past 200 and i think they are probably right sadly. Sorc isnât meant to be a huge modafocker DPS controlling a boss, it is meant to be some hybrid/constant damage class, thatâs why linker and even pyro goes well with it.
About earth tower, iâm afraid even if Ele 3 is not that useful against that specific boss u mentioned, it is still quite decent in Earth tower overall and if it is to be replaced i would probably put another heavy single target DPS class such as some archer builds, not a sorcerer for sure, unless u have something else to offer besides okayish damage (linker 3 or cryo 3 and so on).
I think u have a really good build (not sure about wiz 3, but may be better than pyro anyway) but u are spreading things that are just not true. Even being a rank 4 class Elementalist brings so much more to the table when it comes to overall damage compared to Sorc considering the long run (Ele C3).
And no matter how many ranks they put in, u will always be casting Magic Missile , frost cloud, Hail and so on due to skill cooldowns which are huge overall. Thatâs why u will never be sustained by only warlock skills as long as their cooldowns remain HUGE.
