So I made an observation while playing revenant, not sure if this is an intended feature, bad design or did I just observe it wrong.
TL;
Interrupted or not fully activated utility skills on some legends will lead to not having the desired effect of the skill(which is normal) but will also lead to the definitive loss of the profession specific resource required to activate any weapon and utility skills. -> Huge downtime in being able to do anything, or just autoattack 5 seconds after using any skill (without swapping legend). Get an expensive utility interrupted again after legend swap and you can’t do anything except autoattack for a long period of time.
;DR
So upon interrupt revenant loses the energy required to activate the used utility. Relatively costly utilities energywise that have a cast time, such as Pain Absorbtion on Mallyx and even the leap on Mallyx, are fairly often interrupted. By interrupting these utility skills the revenant is basically unable to use any other weapon skills or utilities without swapping legend, rendering them partially in a state of daze where they can move around and dodge and maybe throw some autoattacks.
This problem occurs fairly often in pvp if there’s an enemy thief, DH, warrior around or the revenant is engaged in a team fight. You will get stunned/dazed in pvp, that’s a fact. You need stun breakers for that. Unlucky though, the stunbreaks are not only costly, the skill effect has a cast time. This makes you waste your energy on defensive effects, which you do not gain apart from the momentary stun break, at the same time negating your offensive capabilities.
This could actually mean that sometimes by resolving a lenghty daze or stun with an energy-expensive stun breaker AND being interrupted again during the channel of the stun break will be counter-productive in the long run, as you will lose the energy consumed for a defensive utility. Same applies for any utility that costs energy and can be easily interrupted, especially after swapping legends when you have no means of acquiring that energy back.
Related to this problem, if you stow some of the utilities, such as Empowering Misery (heal), Rite of the Great Dwarf(elite) and Pain Absorbtion (resistance + stun break) you will not gain the skill effect, which is normal, but you will lose the energy required to fully activate the skill. I understand that without the definitive energy loss utility skills such as Pain Absorbtion could be abused as an infinite stun breaker. Easily fixable though…
Universal energy threshold (eg. 30 or 35) for stun breaking in any legend with any utility skill could solve the problem, making it possible to stunbreak with an offensive utility. It’s not like Pain Absorbtion or Riposting Shadows have an internal cooldown either…
Final rant: If any other class is interrupted should all of their weapon and utility skills (except AA) start loading a daze-like timer before they can be used? This is exactly how it feels like to play revenant at the moment if you are playnig against a daze/stun heavy opponents. As a reminder, while other classes are being interrupted the single skill used will go for a short or full cooldown. Only exception are thieves, but if they run out of initiative, they can just chain 7 dodges and be alright.
Any constructive and conclusive replies/feedback are welcome.
