Here is MY suggestion/idea in how to bring back Fair Play & Balance to the game War Commander;
Level 30 unlocks - Basic Unique and non-Elite levels above that
Level 35 unlocks - Basic and Elite levels only
Level 40 unlocks - All levels including the Omega
Why? This will prevent players opening 2nd or more accounts to abuse lower levels with Unique type units, as to prevent them gaining a MASSIVE advantage over others even though their own level of a 2nd account or brand new player of being an extremely low level player. Like I mention above it will STOP the abuse unfair play let someone is only mid level 30s being able to smash long term player's that have reached say level 45 or above with Omega level units. Doing this will prevent players abusing PVP event for XP gaining massive amounts of XP from players of say 40+ that have a decent Defense in place to protect themselves during such events or outside of it.
Also, it's a GREAT opportunity for Kixeye to sell their recurring BASE UPGRADE PACKAGE that sells for about 200 Gold to instantly bring ANY player's level up to level 40+, and in so doing with the above suggestion/idea will allow them to unlock ALL levels of Unique units ( EXCEPT: They must have collected ALL the parts for such levels before being allowed to build & upgrade to such levels : Basic, Elite and Omega).
They could also promote that instant base upgrade package cost for the following levels of buildings + the usual units they sell along with it'
50 Gold - Brings the player's level up to 30 ( Unlocks Basic Unique levels)
100 Gold = Bring the player's level up to 35 (Unlocks Elite Unique levels)
200 Gold - Brings the player's level to 40 (Unlocks Omega Unique levels)
The above suggestions for the long way or quick way is a WIN WIN for both the Long term players and even for Kixeye because it brings back Fair Play & Balance to War Commander, and they could replicate for their other games too. Why? It allows Kixeye to make frequently MORE money from new players or ones that open up 2nd accounts that instantly want to build & upgrade their newly acquired parts for their Basic, Elite & Omega levels units. While at the SAME time it will HELP retain long term players that have spent Gold over a number of years knowing that any new player can't just instantly have Elite & Omega level Unique units via the help of others, their main accounts or Clan members to unfairly have such level of Units to smash other player's base & units without first bring THEIR OWN levels up to 30, 35 and 40.
Even with my suggestion/idea players can still gather ALL the parts for Basic, Elite and Omega level of Unique units, but they CANNOT build or upgrade such units until their own player's level reaches either 30, 35 and 40.
