Infernal Character Effect (MTX) Suggestion

I just noticed today that the Infernal Character effect is on sale today, I wanted to buy this & the Arctic effect however I cannot get over the very "static" looking models on these effects.

Look here to see what I mean:

The hand model just looks very out of place when the character moves (same for Arctic effect) and it's putting me off buying these MTX.

Is there any way you could change it so that the effect simply rotates around the character OR the hand disappears when the character starts to move? Would buy in a heartbeat if this were so.

Thanks for reading.
