I agree with Kayen, the new tools that are out are outstanding!
I had an idea for a semi Trilogy // semi old school // semi pvp-ish server.
-- Giants Vs. Dragons = They just kinda dropped it...
-- Gods = They never really developed Deities In Game. How about a Core-Of-Grey Spells, then deity related advanced spells for the various classes? This would differentiate classes: Dark Elf Cleric anyone? The questing possibilities here would be pretty cool, extending into Trading Factions as well!
-- Remember the old Giant Faction Grind // or the Dragon Faction Grind? Have areas like the Court Yard in Skyshrine that are PVP areas... the Dragon Faction people can choose to enter the Court Yard to protect it's denizens from being faction harvested by Giant Faction hunters. If the Giant Faction Hunter wins a PVP combat, they get extra Exp, and Faction; then they can kill the denizens for extra faction and gold // drops etc... and of course a place over in Giants Ville for the Dragon Faction Hunters to go. Whats that? You are a CANDY ASS...? FINE! Go do it the old fashioned Grind Way! Still a perfectly cowardly option
-- Add in Mining, like Shards has...
-- All of the races are an option...
-- Toss in a couple of "new" class combos...Ogre Mage anyone? Purely a flavor thing! Perhaps add in a Barbarian Ranger that uses shamanic type spells...? Just a bit of extra flavor, nothing unbalanced.
-- Re-Vamp all of the old Antonica // Kunark // Vellious zones to be inline with later expansions, so that progression feels "Tight" rather than 'Ugh..not this old ass worthless zone!!' ... Can you imagine Halls of Testing fully revamped for much higher levels, but having kept the old flavor, old quests etc...just all of it Tightly Updated? How about Derakor fully updated for the higher level etc...? Plane of Hate // Plane of Fear anyone? Add in the extension to Antonica that SoD brought, Valdeholm will be needed as the giants need some extra turf...etc
-- Put in the ball busting effort to Fix Enchanters...make them the hero's of old!
-- Put in the ball busting effort to Fix Clerics... "Psst, Mr. Ench...I got you bro..Don't F*ck Up kay?" As an old cleric...I remember those days in Plane of Fear...either I would /tell the Ench, or he would /tell me... and suddenly all hell broke loose, BOOM! heh. Bring some of that back! The Cleric Era of GEAR IS GOD = USE only 3-4 second Fast Heals and Just Spam the Piss out of them! ...!?! Rebalance that... CH should be one of those trusty needed options you reach for regularly... but fast heals can be there too, and of course HoT's. Bring back the excitement! Make what was old, VERY New again, with a few twists here and there...
-- Bring back OLD Cazic...but update it to fit smoothly into the classic but new theme...PAW, ...etc... you know the old zones that got messed up bad from updates...
-- Fix Monks...make Monkly Pulling an Art form again!
-- Fix Wizards...if I hear another wizrod tell me "I ain't holding back my blasting, and I ain't running or nothing..." I think I will puke! They F*CKED Wizards UP! Ugh!
Ok, this wall of text is ....too long now.
Just a few ideas that have been kicking around.
