There are a few issues in the game that need to be addressed. High offense compared to defense is an issue. Testing comps without dropping rank is an issue. Cookie cutter teams that will eventually bore players is an issue. Here are a few suggestions that could greatly improve the game and fix these issues.
1. Let players set our arena defense. This will allow us to play around with team comps without dropping rank. This to me is one of the most important changes that needs to happen sooner than later.
2. Give me a way to see my win/loss record other than giving someone my ally code and having them screen shot it. I want to know which comps are winning or not working on defense. It would also be nice to see your last few defensive hits. Who hit you. Did I win or lose? What comp did they use.
3. Stop letting a higher rank lock in there position by attacking a lower position. You should be able to attack lower rank but it is a cheesy tactic used to lock others from fighting you and stealing rank. Do I use it. Yes. But you should stay attackable while attacking lower ranks and I would love to see this tactic go away.
4. Improving defense, evade, hp, armor. Dps and speed are King. Def isn't viable. The issue is that if you greatly improve defense then it basically makes GW near impossible. The fix for this is either by making GW matching better. The last 3 teams only at your level. Or/and giving players a few hidden slots for either chosen purple gear, accessories, or consumables. These slots would only be viable in arena. That allows the player some customization . Make defensive stats on these items better than offensive stats. This will add to comp variety and alleviate cookie cutter builds a bit.
