The 4-kit Engineer [1] and the Elementalist [2] are functionally equivalent, with the single exception of weapon-swapping cooldowns. Their equivalent functions are just in different places. Each profession has:
1. 4 weapon bars to swap among
2. 4 weapon-bar swap buttons
3. 1 healing utility skill, 3 utility skills, and an Elite
However, #2 and #3 are swapped (except the Elite):
- Elementalist: #2 are the F1-F4 buttons, #3 are 6-9.
- Engineer: #2 are 6-9, #3 are F1-F4.
For both professions, each skill (except 1) on the weapon bar has a cooldown, and their healing and utility skills have cooldowns.
The big difference of course is that Elementalist weapon-bar swap buttons (F1-F4) have 9-15s cooldowns (depending on how may points in Arcane), while Engineer weapon-swap buttons (6-9) have no signifcant cooldowns (like 2-3s).
As a result, Elementalist weapon-swapping cd means that you are penalized somewhat for switching to another attunement – say from Water to Fire – by not being able to go back to Water right away if you need to.
For example – say you’re spamming Shatterstone (scepter 2) to build up big stacks of Vulnerabilty, then switch to fire to do some Vuln-buffed damage, and immediately a damage spike hits your group and you need to switch back to Water for AoE healing – but you can’t for another 6-11 seconds (an eternity in combat).
Hence, Elementalists are incentivized to use a 5-4-3-2-swap rotation, cycling through all their skills for maximum throughput and cd usage (not that all do this, just more of an incentive to than Eng), whereas Engineers are better able to pick the right kit and right skill for the situation at hand.
For example, say a Grenade/Bomb/Elixir Gun engineer uses one or two Elixir gun skills then swaps to Grenade kit for more damage, and immediately a damage spike or condition bomb hits the group and you need to swap back to Elixir gun for AoE condition removal and healing (assuming their individual cd’s are up) – you can. There’s no weapon swap cd preventing this, just individual skill cooldowns.
You still have to play smart and save those individual skill cooldowns for when they’re needed, but you aren’t prevented from using Elixir Gun 3 and 5 because you just used Elixir Gun 2 and 4 and then switched to another kit. Your tactical skill choices aren’t stymied stymied by the long weapon-swap cd that elementalists are.
Yet, the Engineer is not considered OP because the actual weapon skills still have cooldowns (although on average much shorter than the Elemantlist weapon skill cd’s – max 25s vs max 45s). They’re not spammable and you still have to use them smartly or find them on individual cd when you really need them.
Would it be the same for the Elementalist, were the Elementalist to have its weapon swap cd’s dropped to the same as the Engineer (2-3s)? Less clunky, less artificial barriers to skill selection and use, more incentive to choose skills strategically/tactically in response to the combat circumstances rather than for cd-optimization, but still limited by individual skill cooldowns.
Thoughts?
