If you raid a private farm for 200k per hour, or park 200k troops in your garage, it comes out to exactly the same. So pointless to only address raiding.
Let me see, most teching is done where 1 player raids 20-40 accounts privately. Some teams get easily to 400-600 of these acconts, just to benefit 10-15 accounts.
Personal or alliance garage accounts you might find 1 or 2 or not at all as it is easier to park in village holding diet plan.
You want to debate about techs, but forget that some players actually agree on playing with litttle defense on account and offering free crop to park troops from alliance. If they had to play as farm, they wouldn't even register on a server because they simply refuse to play as farm. It is their choice and it is not forbidden by rules, so no point to forbid them to garage any kind of troops as they choose to do so.
As 2nd remark, you only want to limit garaging for WWK. If you think that is only troops garaged, well....
And if you plan to go to LOT as ambassador and present your personal ideas and vision on a subject only, you better skip it as you should be representing community.
Your post is 80% about forbidding WWK to be garaged on few accounts where the general tech issues are 95% about massive numbers of accounts set up to be raided. All you write about that is having a limit on raiding in alliance? Wake up, real teching is done outside alliance by creating alliances full of tech accounts so there is no limit on raiding at all.
