Key Systems Breakdown
Hero Progression System
Problem:
Too large of a gap between players power levels and ability to have success in combat or for the game itself to be competitive in PvP and PvE instances, especially for players that are high spenders. Inflation in all aspects of the game (bonus source distribution, combat impactfulness ratio, troop generation, player's general power progression & economy balance) were out of control and players were also dealing with numbers so large that it becomes hard to grasp any value/meaning from them.
Design Goals:
-
Reset game Meta and overall game balance without disrupting spenders ability to have success
-
Increase mid/low-spender engagement
-
Prevent top-end power spikes from breaking matchmaking while maintain pay to play advantages
Solution:
-
Full Meta reset for the game to control power creep inflation by introducing new themed bonus types, buildings, currencies, general theming in the game (Dark World was one instance of this).
-
New bonuses would scale to be 1 trillion times more powerful then previous ones (old version would take a value of 1 trillion to equal a value of 1 on the new bonuses)
-
Added event-based progression injections
-
New theming across the game to reinforce the reset.
Tradeoffs:
-
Temporary solution to a large issue. Power creep will happen again, just extends the timeline for this while starting as close to zero as you can with an established meta for power creep.
-
Creates additional complexity with problem solving for the game. There are going to be servers that have not reached the reset yet, so need to know progression intimately for the game to know underlying issues going on and what is being impacted.
Learning:
Progression pacing must align with content cadence and less can be more in terms of impact in order to slow power creep, otherwise you get to the point to where it accelerates uncontrollably too quickly.
