Like many people here I don't care what others are doing. I'm going to fight a C-hog the same way whether the guy earned the points or vulched a shade account for them. Is it a classless thing to do, yup! But those are the guys I add to the ignore/squelch list and no longer have to deal with.
While HTC gives me ways to handle these things they should still be a bit more proactive in situations like this. After all it is their reputation they have to protect. "Cheating" is a big no-no and is stamped out as soon as it is found out to be happening. Those involved are sent packing. We all know this because HTC MUST protect their reputation. Not many people are going to play a game where cheating is allowed and runs rampant.
Now is score padding, perk farming built the way the OP is describing bad enough to hurt their reputation? Is score important enough to the game play mechanics that they should worry about people working their way around the conventional way of earning points/perks? After all this is a game and there has to be a way to see if your "winning" or not and that is what score does for you. If someone is "winning" with out having to work for it like other do is that fair? Would it be enough of an issue that it could hurt the game/subscriptions?
Perks are different. They are there to curb the use of more exceptional equipment, but isn't farming them in another arena defeating the purpose by allowing more perked rides than would be normally earned? Granted the number may not be big now, but what if when the summer hits and "kiddies" show up and this becomes the "way" to earn those perks they normally wouldn't be able to get and start unbalancing the arena. Would that be a big selling point for the game or again effect the bottom line at HTC?
We can voice our opinions here all we want. HTC KNOWS we are a very small portion of the over all subscription base for this game. HTC is the one who must decide if this matter is something they should act on, and what that act might be. Personally I plan on continuing to give HTC my monthly payment until they close the doors on the place, whether thats in 6 months, or another 10 years. It's all up to HTC.
