1) requiring a separate login for beta forum is an... interesting design decision
2) Only changing SCs and WTs is nonsense. Like planetofthehumans2 called out, the buildings all work together. Are you really suggesting that you're going to have SCs and WTs have multiplicative, capped impact and the others be additive? That would not make it through even a brainstorming session in my product group, much less to a design doc or beta testing. That proposal should have been nerfed from the second it was created.
3) The ranking system is the biggest issue. We're in a season right now where there are a bunch of folks that moved up from platinum to diamond and cant keep up. so its super slow in the top league. For other seasons we're with a bunch of competitive guilds and someone gets bumped down to platinum that shouldnt. Put limits on the number of guilds in each league as many others have suggested. These limits could be tied to percentages of "active" guilds on each server.
4) I understand why cross server battlegrounds is technically difficult or even impossible, but that would be way more interesting. Larger pool, more evenly matched guilds, you dont "know" all of the players, and people actually fight
5) If you want to get rid of farming, introduce a mechanism to encourage or force guilds to team up - cumulative scores, mechanisms to support guilds you're teamed up with, etc.
6) This low of a cap will massively reduce participation. A lot of people that are for this change are calling out the benefits of being able to spend less time. The amount of time you spend is a personal choice. If you have issues with self control, perhaps therapy is a good option instead of pushing Inno to limit everyone else based on the amount of time you want to spend on the game. Inno effectively capping the time in GBG is really confusing. You're creating a disincentive to be online for more than 10-30 mins - I'm estimating that max fights for a person that gets to 100 attrition is 300 and you can do ~15 fights a min if you're in a good flow. That would be 20 mins of activity, but buffer a bit for swapping troops as attrition gets higher. Why are you forcing that limit?
7) Perhaps most importantly,
almost 70% of people in the poll attached to this thread are against this change. Will you guys act in accordance with what the majority of people want?
