I genuinely hate the new WAR animation.

So it's not at all a matter of them not being able to do it when it is a matter of the superficiality of the end result does not justify the cost of the means of achieving it, especially when there are other potential solutions that could give similar end results without such cost.

I disagree. With it, the skill would arguably look iconic. Without it, the skill looks merely ridiculous. And it's not unique in that regard. To thus constrain all future skill animations that could benefit from VFX with multiple points of origin in a single stack (or use a further VFX stack), or leave them similarly half-assed, shouldn't be an acceptable solution.

Most skills already use two "stacks" of VFX, usually holding 2-3 VFX files each, for the caster and on-hit or at-target-area. Each of those separate VFX files is either placed at an absolute location of origin or a relative location (i.e., about the target or player). In this case, they could easily use a generic aura-flamed axe if the problem is querying for a particular weapon appearance to associate with the spawned VFX. The only thing that remains thereafter is to allow a third stack, whereby you can have a caster stack, at-target-area stack, and on-hit. Voila.

If that takes a revision to the system, short of being truly impossible, it's probably worth it. It's a modern MMO that already plays it safe in nearly every other possible way. They don't need every excuse throw their way.
