I can deal with a slight lessening on some things, but I very much disagree that they should look as mundane as simply running or making standard weapon attacks. Visual feedback is super important. Dash is something, especially, that I see some people suggesting that they completely remove all effects for, but I think its really important that players are able to tell that another creature dashed without inferring it from general 5e knowledge or reading logs.

Things like weapon trails, impact effects, and air distortions can successfully convey a physicality to the move compared to magic, while still allowing the special actions to be easily discernible from standard attacks or movement.
