As much as I hate to say it I was actually pleasantly suprised by the gamemode. It's far from perfect but despite all of the issues, I have still enjoyed playing it.
1. Fixing the spawns
Sometimes you die next to your teammates, but then spawn on the other side of the district in the gas without enough hazmat suits to make it out alive. This is really frustrating and is probably why so many people dislike the gamemode.
2. Fixing the crashes/disconnects
My friends and I have noticed that the game sometimes crashes or disconnects randomly upon entering a RIOT district.
3. Adding more rewards
This would really give an incentive for people to play the gamemode. It feels like reaching lvl 5 just to get 1 weapon skin is way too much. Would be nice if you guys could add more rewards to the contact (at least 1 per level). I know this is just a beta test but still.
4. Make some of the roofs inaccessible
The City Hall and the Church are two spots that seem to be incredibly overpowered. There is only 1 way up and it's incredibly easy to defend. Since there aren't any grenades in the gamemode (for good reason) it's really hard to take over those two spots. My solution would just to make them inaccessible.
5. Make the rewards account bound
I'm not sure if this would even be possible but it would be nice to have the progress towards the contact be account bound. Some of us are sitting on multiple characters and would like to have the items available on all of them.
6. Hazmat suit cooldown
I feel like having a 1min cooldown on the hazmat suit is a bit too much. IMO you should remove the cooldown (or reduce it to like 15s), but limit the amount of hazmat suits you can have to 2 (also reduce the spawn rate). This would reward the player for being smart with the usage of their hazmat suits.
Side note: Please make it so that you aren't forced to use your hazmat suit instantly upon spawning in the gas. Just give the player 1 hazmat suit to use whenever they would like.
