Maybe, but before the Arc and hyper-leveling, GBs were part of the game, not the whole game.
The Arc is still part of the game. A part you cant ignore, but still only a part. It effects a lot of other parts of the game, but still, there is so much more in the game.
Further, its interesting that we (the players) started to find solutions to the Arc issues - let me try to explain what I mean -
For a long time the Arc troubled me. You cant realy fight over a spot against a player with high arc.
But lately more and more guilds started to support their guildies with a 1.8(+) value thread (i.e. you post your GB into it, and get a 1.8 value for a spot from a guildie with high arc) and this (IMO and experience) reduces the snipe issue a lot. For the players who dont have high arc they still cant take the 1st/2nd spots, but on the other hand they know they can have good value on thier own spots. So they can kick all thier sniper (not)friends, and remain secure within the guild who will help level thier GB's in a faster way then they could do alone. The Arc, in this way, within the guild, support and advance other players.
Yes, this solution works only for guilds who support this, but the idea now is out, and it starts to root.
And yes, it does not take care of the root problem of the Arc, but it does help with the symptoms.
