Absolutely fantastic idea Dawson. The only question I have is, why not let them choose? It would let players have a chance at some slight sort of freedom and let them test new weapons they may have yet to acquire.
Feel like the "Armageddon" will be overpowered because since there is going to be more ammo then usual and everyone will have the same class so everyone will shoot all the predator missile at each other boat the round wont last long and not sure about this but maybe cause lag with all the missiles if the server is full like that doesn't cause a lot of lag already. From that aside great idea! Well if we let them pick what class there are going to be 0 picking the weaker classes and only the really strong ones. Also the more experienced players will have a idea of what weapon then want but if someone started playing not so long ago they probably wont have an idea of what they should pick and it will be unbalanced.
Like every single first-person shooter ever? Remember it's only one round, this will only be every once and a while and when it does do you want to get stuck with a class or be able to choose? Perhaps changing your class costs you in-game money or tokens.
I am going to throw my honest opinion out there. Like a lot of events out there, this is just a remake of it. There's no point in having two events where you have to use specific shitty weapons, we already have an event like that. This is literally just the same event except with more weapons.
It's the fact that all those events revolve around have specified weapons, why would we want NUMEROUS events where we get glued to weapons, frankly it seems like all of those are generally just like the single weapon round. Do something different, but maybe an event where it's not just like the other existing ones.
I am a very simple person with a very simple mind, I don't have enough ideas to spam across the forums. I'd much rather give my honest criticism on ideas that are simply the same exact thing as events that Donkie already implemented. I'd much rather see Donkie use his time on projects he's working on and things that will seriously help out the gamemodes (map, helping Counter with TTT, fixing jailbreak). I know we need more events, but what we need are less ideas that are nearly exactly the same as already implemented events. Donkie doesn't have the time of day to read every single suggestion you post, he's a busy man with his life. Just he wants to work on projects in the community like new and creative events, not something so similar to something he has already worked on.
