I think SE can alleviate the problem of leveling too fast by increasing monsters HP and lengthening the fights.

I agree with the OP and many others in this thread that leveling 40-50 in less than a day (getting nearly 1 level per hour at the Ixali stronghold) is too fast. I believe it's because in my 8 man parties, we are literally pulling 5-6 mobs at a time and AOEing them all down for 500-1k exp a monster. Given that you only need 100k exp to go from 49 to 50, it only takes an hour of AOEing to ding.

If the mobs survived longer we'd probably see the exp parties go back to chaining 4 or 5 before losing the chain instead of the chain 10+ I'm seeing these days.

Possibly could switch full parties back to 6 members as well, 8 just feels kind of zergy to me.
