What about a once a week boss reward. Every week, you log on, and you go to a destination. You shift around the zones until you feel it. Faint, but it's there. The distinct thud-thud-thud vibration of footfalls. Massive footfalls. This is it. You'd best have brought your cojones. Now you've found the area, you need to scout it's trigger. It could be anything. A chest. A relic. A marking, that when read out summons the beast (imagine using voice chat to do this, seriously cool). I'm going to use one example. Turns out you have to activate the mini spires dotted around the hellmouth. They burn fiercely, and you feel your strength ebb. A crazed shriek burns the air, and the ground itself shudders as something drags itself to the surface. An ogre climbs out of the pit. You caught them breeding Phogoth... You banished gulrot... Seems like you missed one. This guy is HUGE. Like comparing a shank to a walker. You don't have time to prepare, and all hell breaks loose. The eye blasts are less of an auto fire, more of a cannon blast, maybe even a mortar that fractures. The smash kills you in one, clearly. The guy would probably put you 30 foot underground. Those pillars are also against you. Your strength ebbs nearby to them. So you cut a mad, zigzag dash across the terrain, dodging blast after blast and spire after spire. Your targets are his joints. Take out a knee, he slows. Take out an elbow, his smash become weaker and less frequent. You can even take out an eye and his accuracy falls. This is the biggest difference needed here. These things need to be damn near indestructible unless you hit the weak spots. I also think it would properly cement each class's roles. Defenders keeping people going and providing true support through buffs and respite points, acting as that ever-needed shadow of backup and frontline artillery. Voidwalkers decimating hordes of enemies, cascading orb after orb in the wake of purple rain. Bladedancers zipping around, dragging the enemy here and there to split the horde and divide their attention before striking at the heart. I love the idea of a call to arms for all guardians in the vicinity. Having all 16 guardians hammering a skyscraper sized ogre, or a scuttling vex leviathan, or a cabal tank (think the Imperialis from warhammer) or taking on a whole legion of fallen at once... These should be of the difficulty whereby it's like you playing skolas at level 32. 3 levels down is not impossible if you communicate, but you don't stand a hope in hell if you don't. Though I guess that means PUBLIC VOICE CHAT IS NEEDED HINT HINT. Rewards? A mega box of unique loot. Proper trophy armour that screams "i took on the biggest, baddest bastard out there and won". Massive XP gains. Weapons a guardian could dream of. A buff comparable to Nightfall's. The list goes on. Make no mistake,these aren't raid rewards, where you can do it with 3 if you work together, and who cares if they need carrying a bit. I'm talking the level whereby if your head isnt on a swivel, and you aren't doing your part, you're down, and you failed. Your team needs you, and you need them.
