GA encouragement

To legitimately be “equally challenging,” both players would need to have roughly equal zetas, gear 11 & 12 characters, arena ranks, mods, teams, legendary characters, knowledge of the game, and desire to compete in grand arena. That’s just not going to happen. Even the areas I mentioned that the developers can match are likely too much for their servers to compute in a reasonably short period. And so instead they match by power, which may be a bit simplistic compared to all the factors that it would take to ensure “fairness” or “equality”, but does a generally good job of giving fairly competitive matches. But players in the top 50 of either arena (or both) and paying players are usually going to do better in grand arena as well.
