I wish there was a server command in console that could change the round time and how much time you gain on cap. I would really love to see round timer being revamped for 5CP, because at the moment and forever, round timer means nothing, heck you can even remove it from the casting hud and keep only server timelimit, just because it doesn't affect gameplay in any way, you'll probably never going to see a team holding for 10 minutes and waiting til round timer runs out. What I want to suggest is quite game changing, but it's what I had in my mind for few months now.
What I would like to see is a round timer being reduced from 10 minutes to 4, but on Capture it doesn't reset back to 4 minutes, it adds up 1 minute, but it won't go further than 4 minutes. What if the timer runs out? Simple answer, round resets, none of the teams receive any points What does it potentially changes?
It makes stalemates less frequent, if lets say on mid both teams lost their medics, but team A won mid, they secure Mid and 2nd, now with the time they got with caps, it's roughly back to 4 minutes, during that time both teams have time to build an uber, get a pick, make a push. No more 8 minutes of waiting til something happens.
Of course defending team is heavily favoured by this, because they can just go full Highlander mode and do nothing, wait 4 minutes, round resets and they don't have to worry about backcaps or them failing, so if that happens, defending team who didn't attempt to push 2nd gets a penalty for the next round, their freeze time is extended by 2 seconds, BUT, that is only if Defending team is leading score wise, if the score is in Attacking team's favour, they get penalized instead.
This is what I had in my mind for a long time now and I know it might not sound too convincing, but I just wish 5CP maps were more focused around the Round timer, because at this very moment round timer is pointless and it doesn't do anything in 6s 5CP. The purpose is to reduce the amount of stalemates that happen nowadays and make matches much more interesting, and to some extent prevent casters from dying from boredom.
tl;dr: Give purpose to round timers, reduce from 10 minutes to 4. On cap adds 1 minute instead of full reset, can't go further than 4 minutes. Defending team (the one who doesn't control mid) who doesn't push will get penalized with additional 2 second of freeze time on next round start, as long as score is in their favour, if Attacking team won't push and they are leading, they get penalized instead.
