My honest opinion this game mode is going to be a failure.
1. It requires to many players
This is bound to make a huge split on the players on game modes. Making Que times longer.
While this might make for more epic battles, it really does not make for an enjoyable experience when your fighting a large number of tanks.
2. The maps are way to large.
This makes the split teams unevenly making onside battles.
Slow tanks can struggle in some situations.
Big map makes you travel time longer meaning less action.
Do I have to say more. A prime example why the rampage mode failed is this game mode.
This game mode is not for the average player and many regular player will be turned of immediately
4. Battle length.(personal suggestion)
While a few players might enjoy long battles I find my self enjoying the 15 min time limit of random battle. It might not be an issue for some people but I personally am turned off by it.
5. ITS NOT FUN.
Simple enough I did not enjoy it. I was a game mode that really made me wish it was over before it started. Having to play for 20 min and not make any profit is not something I call fun. A negative is that this game just like the failed rampage mode is that it will be limited to tier 10 tank that don't really make any profit for average player and even top player will find they will not make much profit as well.
1. 30v30 not going to work and will only serve to split the player base. Like rampage it will be a game mode that no one will play.
solution. Make it small size battle with a smaller number of players ex. 3v3 or 6v6. With the small number of player it makes re spawning more enjoyable so it does not feel like a massive tank orgies. This would also make the player base hit less of an impact.
2. Time. Playing a match for 20 mins and not making profit sucks
Solution. For this make the game mode short and fun. The average match should be between 7 to 10 min
3. Profit\Tier. While this mode you can only be competitive at tier 10. We know tier 10 don't make money.
Solution. I find my self also enjoying lower tiers and with the smaller player base required for a battle you can have a single tier mm if it's 3v3. I would find this fun specially platoon vs platoon with re spawn. Having lower tier means you can also have game that you can profit on.
That is my opinion so far, with this I will let the development know that this game is bound to failure just like RAMPAGE. The fail mode that nobody played after a month. While I'm glad to see something new, this is a step to the wrong direction on my opinion.
