I find it interesting the there was no noise about bots when it was just whales and farms. As soon as bots and helpers are put into the hands of the 'regular' players, people are up in arms about it. Whales leading the masses to what is best for them...and they follow. They follow because you guys tell them it will save the game, they can start winning, they can earn more...but really the only people who will truly benefit from these changes are the ones who really don't need it.
It seems similar to the gun debate...in that if you make guns illegal then only criminals will have guns...lots of them. the only people who will follow the new terms are those who follow the rules...OR are using the XBOT service as Sylar has decided earlier that he would respect the terms (when he disabled his service in Modern)...so the 'regular' players will now lose access...but that won't stop it. it'll be back to the status quo where only a certain class of player will have access to these tools (whales)...which is, interestingly, exactly where we were at before bots came to the masses and whales started getting beat up in diamond/champion.
Tinfoil hat aside...If this proposal could guarantee any kind of equal enforcement, then i'd vote for it just to move on...so i have a counter proposal for you...instead of changing the terms of service, simply disable the 'ongoing_match' API endpoint. this will make sure that there will be NO access to banned tools during a battle. Or they could set it up to where it would only return Wild Ranked battles instead of every match.
Personally, i don't really think bots are the root of all the problems in the game or ecosystem. I would offer that 15 million Chaos Legion packs hurt this game as much, if not more than individual accounts botting...but that's just me.
