Grail, is it overpowered?

After playing a game with Ivan, which just ended, I strongly disagree with him: 1. If it weren't for the Grail, I wouldn't have had any theoretical chance to do anything. On 3 respawn points, only 1 mini-Zephyr appeared, without any hiding spots, and the 4th respawn point was in a dead zone. So, sometimes (although rarely), the Grail balances the game, rather than being an absurdity. 2. I dug up (and did dig up!) the Grail in a game against a live opponent - for the first time in my life!))) So, don't put me on that hellish Schindler's list.
