Your right to certain extent about cover being cover.
There is nothing wrong with that if your playing against a friend or a casual tournament at the local store.
I don't know how familiar you are with the scope and depth some people go to for some of the larger tournaments. I know some people that fly across the country and and other continents to go to tournaments. Sometmies dropping over a grand to go. I know I have spent over $500 going to national tournaments multiple times. One of the most annoying things that came about in the early days of these events was the set of rules would change from place to place. This led to a lot of arguments. GW was good with FAQ's for awhile but were slow recently a independant group came up with a fairly comprehensice set of rules to cover most sticky situations.
There are two sets of rules arguments RAW (rule as written) and RAI (rule as interpretted). Most of the time rules are judged in the favor of RAW because it makes sense. The reason why is there is a million dofferent opinions about "fluff-wise" a rule should be rules a certain way. RAW good or bad is a literal intrepration good or bad its the fairest in my opinion.
That being said I mostly play "as if" meaning as if I am in a tournament. Literal interpretation usually wins out in a rules argument because its in black and white.
If you want to play cover is cover go method go ahead as long as you have your opponents permission, but don't expect everyone to play that way.
That being said its a game have fun!
