COTL Loot run tweaks

Overall, I love this loot run, it is some of the most fun I've had with this game. A few tweaks would be helpful listed from greatest to least importance. The stats of the character I have will be at the bottom (eventually).

1. There's a cave that teleports you out of the COTL as a one way ticket. It is far too easy to access and it ends the lootrun. I'm pretty sure it's the cave used for Beyond the Grave, and it's located at 350 29 -4933.

2. In the defend section near the farm at the bottom of a canyon with Elefolk, outside mobs attack the objective. Harpy Archers are outside the arena yet can easily shoot to the center. They're also stronger than the Elefolk themselves. It was confusing why the health of the objective was evaporating despite killing all the lootrun mobs.

(This is also a feature of the attack event with the parasitic slimes where Jinko's often run into the area. They are also stronger than the lootrun mobs, but it seems to adjust the event to the right balance of difficulty.)

In this area it is easy for Elefolk archers to hide behind far away objects and attack it, which may be hard for non-ranged classes.

3. The lag for the lootrun increases dramatically whenever the new Gargoyles are used. This is both in the attack challenge near the Colossus and Chiseler's Cavern. It is at times unplayable with it freezing my position for upwards of 30 seconds and letting me run around. I'm pretty sure this is due to a mass of the mobs, because when I kill all the Gargoyles on my way through the cave the lag wasn't as intense.
Broader Context:

For the broader context of this update, this lootrun is what I need to interact with the rest of the systems. I have a pretty bad build (2.3k DPS, 13,000 health, decent health Regen, 35/4ish mana Regen, full boltslinger except a grappling hook and a lot of speed). I haven't been able to get past 6 challenges in the Rodoroc lootrun. However, this loot run is perfectly balanced for me and is giving me better loot then I currently have. I think this could be a way that players like me who mostly played through the quests can get the loot to participate in the new raids and world events.
