So, here is my feedback after trying Battleground for a few weeks in Beta and "real" worlds:
- This new game is not bad, but it still needs some tuning. The biggest issues are that it is too much pay-per-win and needs to be attended 24/7.
- The ability to add and delete buildings while under "siege" is way too overpowered. The typical scenario is: put 3 palaces once you take the sector, replace palaces with traps once somebody starts to take over the sector, while the enemy advances, keep replacing traps with fortress at will, remove everything just before the sector is taken. Construction/demolition features should be locked during siege.
- Since sectors stay locked for 4 hours only, people willing to play at night have a great advantage by taking lots of sectors while others are sleeping. A few "night shift" people can easily win all the central sectors by using siege camps. A 8 hours lock countdown would allow for a more relaxed gaming experience, or maybe the battlefield should be paused at night.
- Being matched with the same guilds over and over tends to be boring. There should be more randomness in the matchmaking algorithm.
- Since it greatly affects the leaderboard, MMR should be visible.
- I understand the "quadrant" logic behind sector naming, yet having unique sector names would make team management easier.
- There should be a log of player actions just like in the gvg
- To avoid diplomacy issues and wastes, it should be possible to allow only a few members to place a new "siege"
- To avoid people taking sectors at the wrong moment, it should be possible to "lock" a sector, preventing anyone to fight in it
Hope this helps.
