Is there currently anyway to attempt to keep enemies at pole range either while using pole range weapon or not? I know there is engage failures I've seen those but can you engage to just pole then try and stay at that range?
Theoretically yes. Practically no. You can theoretically get to pole range then use HANGBACK. But its almost useless against anything you can learn from.
Pushback may be looked at during the engagement rewrite, and taken care of during individual weapon rechecks or we may just have to continue campaigning for pushback for our pole ranged weapons.
