No, it wouldn't be difficult.
True.
*poof*
Uh oh...
Well, nobody could say no to objectively better weapon effects. So why didn't we just do this ourselves last week, or a year ago... or do it tomorrow?
We're almost stuck in a limbo. We've been planning to implement particles and newer weapon effects that require new code that would render such improvements redundant. It's always a tricky call as a small team to balance not only work vs yield, but knowing whether the small improvements would need rewriting in the future and be rendered a waste of resources.
I'll bring this up with the team. Perhaps it's time to reevaluate such short term improvements.
