As captains get to levels over 30, I believe they need more time added to put markers on the map. Right now you only give them one minute. I think expanding it to three minutes is fair.

More time in the campaign aswell

I third this! Between keeping up with an active chat and such, I feel rushed when doing dungeons or pvp or anything like that. I've been taking notes from Immerbock and learning to place important unit markers first and then filling the rest out but there's always someone immediately dropping because I didn't go fast enough.

I actually would love to see an option where you can decide how many minutes planning phase you need. When you vibe dungeon you do not need 3 minutes.. or a button "Start placements", like "Start battle", giving unlimited amount of time. :) And this in all game modes.

That would be super helpful. This ^

I would LOVE an extra 30second planning time (3minues is way too much and would make me super mad, also people would get annoyed having to wait so long to place imo) but ONLY if it cut into the placement time. Same for Campaign/pvp it would be annoying if dungeons would were even longer.
Fixing the lag for placement markers to show up would be a great help too OR if we cant get extra placment time, Do not place zones actually meaning people cant place would be great

I would like a slider where I can allocate the time myself. The early start button can be as it is if that's to breaking. A slider would allow any cap to adjust is as they please

can work too, i like this. alot of viewers already hate the planning time, so id love it as an optional thing or slider would be better if it doesnt make overall longer 
[as long as we dont have to hit an extra button and can leave it at a set setting if we want kinda like the gold split, set and forget but adjust if we want on demand]

While I may not be a captain I can appreciate giving the captains more control over battle planning time and 100% support the adjustable time.

I personally love the idea of keeping the battle at a fixed 30min, where it would be up to each captain to decide how much of that 30min they want to spend on setup before advancing to the placement phase for the remainder of the 30min. That keeps the battles more consistently reliable on the viewer side, but also gives the captains the ability to control their setup without early droppers messing up the battle plan.
