I'd like to submit some ideas of what I'd like to see in a dungeon or maybe a 24 man raid.
We always linearly move forward and plow through enemies in dungeons and raids but maybe to add novelty to the formula could we perhaps get some dungeons where we are in a defensive position and instead we have to pull back and retreat into increasingly fortified positions as we hold off an attack? The formula of mobs/boss could remain largely similar but the movement would be backwards.
Lets take lakeland for example, if we got there early and we set up in the forest and fight mobs there until we get overrun (not really but the dungeons animations etc makes us seem overrun) and then we move to the village and so on until we begin to repel the attack and the boss shows up and we kill it and bam, defended. Just an example.
Similarly could we also add something like instanced Dynamis from FFXI where to breathe new life into the main cities for endgame players we could have a story line where the beast tribes start launching attacks on the main cities and the dungeon/raid location is within the city and we have to fight there. This could also be an instanced beseiged like Aht Urgan had open world besieged and holding off these attacks sounds like a ton of fun. I think it would add variety and a dimension that we do not have to the game and can be implemented in instanced zones like most combat content.
Something similar to beast tribes could be a garlemald invasion of these cities in an instanced raid since no doubt we will clash with them in the future and it would make sense for them to launch counter assaults or invasions. Stealth or not.
This would also allow some assets to be re-used since the zones exist.
I just want something new because the tried and true formula is good but its just more of the same every time, so I hope these ideas are any good or if not maybe to get people thinking about stuff.
