Strong in favor. Some thoughts:
- High/low arc is an option for some units in Spring RTS and it worked well.
- I'd assume high arc also reduces accuracy*.
- Conversely, adding low arc to other artillery pieces is a big buff and probably shouldn't be done.
- Option could be added to an existing order button (as a right click, like snipe mode), added under the fire state toggle menu, or added as a new order button entirely.
*Need to test this to establish that firing randomness is angular, not positional.
Technical considerations:
- I'd assume the toggle could be accomplished with a buff blueprint (I say assume because I've looked at buff blueprints for accomplishing about a hundred different things but haven't executed on any of them).
