Enlisted is a fast-paced game, and when you’re hurrying to do things muscle-memory is going to take over. If you’re used to using upgraded radio squads/radiomen, then its probably in your muscle memory to just click as soon as you bring up the option wheel to pick where you’re trying to place your arty strike ASAP. Not to mention there’s a little competition at the start of a match to see who’ll be able to get their arty call in first, so calling in arty as fast as you can is a must.
However this creates a problem where if you switch to a new faction (or if you don’t have the expanded capabilities upgrade yet and use a radioman on a different squad), you’ll click to get through the option wheel… Only there is no option wheel, and you just end up clicking some random spot on the map and wasting your artillery, not to mention blocking your team from using arty during that time.
So, the solution is simple. Just make it ALWAYS bring up the option wheel, even if you don’t have any alternates yet to pick from.
