Okay I run big complex combat encounters. These generally need either multiple small maps or one great big map. Currently 50 by 50 is the standard map size I use, and even that tends to lag. And for some reason the lag gets worse the more roll20 updates.I used to use 100 by 100 maps. But thats just not doable now. One of the biggest obstacles to using multiple small maps is that the players can only see the turns for tokens that rolled initiative on the map they are looking at. Which causes a LOT of problems. I can guess there are some problems with doing it another way. Especially with some of the API scripts. But surely there is a work around. Maybe make it a toggleable option to force and lock everyone onto whatever map the active turn is on. It may be inconvenient but it would at least make running an encounter over multiple smaller maps at least possible.
