For kvk and even cvc the competition usually has equal influence.  And yes training gazillions of T5 or T6 can get you a lot of points.  But it isn't always who ever pays the most wins.  Yea sometimes there will be a competitor that spends a ton ... and well that is just life ... you lose some you win some, but that isn't always the case. 

I know it's not always the case, because, many people just didn't realize how this T5/T6 trick was used against them. What I mean, is that this is probably intentionally made to make people spend money on the game (as soon as they realize it) - just like the arms dealers who sell to both camps.

The game developers one of the things they do is try to entice people to spend money ... they need money to operate ... I would expect people who spend money will get an advantage over those who didn't ... otherwise why would anyone spend any money on the game?

Yes, I agree with that, but when it comes to the point to completely unbalance the game and when it ends-up to a fight for who will spend the most, then it makes things unhealthy, like in my example of the arms dealers.

I've observed that the simple way to win the KVK consists in making gazillons of T5 or T6.

wrong observation... in KVK, troop training don't make points but only troop killing... KVKR is a other case...

If you use a lot your credit card, there is plenty of way to win event... sometime, i see a huy killing all ubers around the pop with a single hit... guy must be loaded with a lot a energy... sometime, i spy guy where statistic say 3 mil troop train, 3 mil killed but fround that the guys have yet several millions troop... troop buy with real money...

In short, money will always give you a advantage for any event... there is no glory to win with your wallet but there is to win by hard work...
