I guess I just have to roll my own prediction? Say I have a drain effect which periodically reduces a bar by X every second. The server ultimately decides the drain (attributes replicated) and I can smooth the bar animation, but unless I predict it there's a nasty lag i both starting and finishing the drain. I already predict the action start/stop locally so there's no lag, but that's built in GAS. Ticking down the bar immediately while the ability is activated needs to happen locally 🤔
