Rook attacks used to be my favorite thing in the game... now I find them quite boring. It's not because they're inherently boring--it's because they are WAY to easy to thwart. When there are only a few people at a Rook attack, it is extremely interesting and fun: there is actually a real threat of the stun/prime attempts failing, and the Rook getting an attack in. Every attack I've been to lately (including one during off-hours this morning) have had enough people there that there is zero chance of failure. I don't even know if the new players have ever seen the animation of the Rook attacking their screen... probably not. I don't feel like my presence is needed, which gives me no reason to show up. It is also insanely easy to revive animals afterwards, so there is not even any reason to do that (there only really needs to be 2 people total doing the reviving.) I think the maximum number of people helping at a Rook attack before it becomes completely unchallenging is somewhere between 10 and 15, which is extremely easy to achieve.
Given the large number of players that are currently looking for something more interesting and meaningful to do than learn skills and gather resources, Rook attacks are a great, easy way to keep them entertained and happy *if* they feel like they are contributing in a meaningful way. The Rook has to be harder to beat in general. Also, maybe if there are more Glitch's present than a certain threshold the Rook could call in reinforcements and become even more powerful. The Rook is currently a laughably weak enemy, and it would make things much more interesting if this wasn't the case.
