This map has been playtested and pug'd in Highlander recently to some fairly good reception so far! I took place in one half and got some general feedback bullet points to share from the players involved. I'm directing other players to this thread too in case I misstated them or they have more to add. Keep in mind only one half was played and in HL rather than 6's, so strategies are liable to change:

*Underneath the point got the most point of criticism. It can be held very strongly by a Soldier or any class that can deal splash damage, thanks to large number of pillars underneath. The elevation changes/slopes were not an issue so much as the pillars, which could cause a Soldier to hold the bottom pretty strongly on his own.

*The cave 'windows' on either side of the point were frequently used by Snipers, but it's pretty hard to actually jump the Sniper as Soldier. Snipers can be spammed out from splash easy, but they can just as easily back up and get buffs and then walk back in. Some players suggested opening up the cave to make it somewhat like Product's cliff: keep a see-through fence as border but at least open up the top.

*There's a set of rocks on the point that look like you can crouch jump from them to the cave 'windows' but they're just out of reach. Players weren't sure if it'd be a good idea or not if the rocks were put closer to the windows so that classes can jump between them. Some thought it'd be a good way to get up to Snipers in the window (as Spy especially) but others thought that a team just capturing the point could then jump up the rocks into the other team's cave and forward hold too easy.

Some general positive notes I had:

*As an Engineer, this map is very fair to minis. The map has very steep elevation changes that force minisentries to look up when attacking the point which reduces their effective range and makes them easily spammable from blind stickies or rockets. Any point where you can wrangle a mini from (like the cave window or battlements) can be easily countered from spam or other Snipers.

*Heavy is very strong to hold on the point, thanks to the medium ammo pack and small health pack just above the entrance leading under the point.

*This map plays very similarly to Warmtic but with Sniper sightlines altered or removed. Warmtic has been played before in HL and many HL players were familiar with navigating Cascade. It's also considerably more optimized than Warmtic; no players reported unusual frame drops.
