What I'd like to see (but know will never happen):
- A complete revamp of the tradeskill system, taking from the old school RSI/you'd better macro and pray method, to one that makes more sense and is more compelling and engaging (NOT necessarily easier). With each trade having a bare minimum of things worth bothering to make and often requiring up to a dozen subcombines just to be able to do the combine for the thing you actually want, EQ's system is more outdated than polyester suits and the Model A.
- No new zones. Instead, adding revamps of existing underused zones and high level versions of those zones. Though he's no longer with the company, John Capozzi (aka Kendrick) was good at turning ignored zones into player hotspots (Velks, Chardok, the groundwork for Acrylia Caverns, etc).
- Originality and creativity. Yeah, I know I'm asking for too much but would it kill them to actually come up with new (not rehashed, not cut & paste, not stolen from elsewhere and implemented retardedly) spells, items, features, and encounter mechanics? Or, to come up with these ideas and not nerf the hell out of them three months later because they didn't foresee players using said spells a certain way (hi Skin of the Reptile/Decrepit Skin/Ward of Tunare/Languor, monster missions). Heck, it wouldn't be so bad if they didn't completely abandon these things within two expansions (Leader AA, for example). I think it's telling when someone is PLing a new toon and chooses to specifically ignore all spells below 75 because "the newer spells are better so why bother with the old ones?". When almost everything at 85 is essentially an upgrade of 80 which was an upgrade of 75 which was an upgrade of 70, I can see the logic in that. (Of course, exceptions exist for spells like Bind Affinity, which has never been upgraded, or port/TL spells)
- This is a big one. Never, ever, ever, ever, ever should a level cap increasing expansion produce WORSE experience working from the old cap to the new one. EVER. Since PoP (the first cap increasing expansion since Kunark), it has always been best to xp to the new cap in the new expansion. PoP had Valor (I did 61-65 in PoV inner caves in 2 days. Was full into 60 when expansion went live and dinged 61 during a Sleeper's Tomb raid), HoH, and CoD (for some classes). OoW had WoS, MPG, and RSS. TSS had the Steppes and Valdeholm. SoF had DSH and Loping Plains and maybe Hills of Shade. SoD had.....Mech Guardian/Beza/Zeka/Fortress Mechanotus, in SoF?!? The hell?? Kunark was different, because many solo classes stayed behind and leveled off old content (dwarves in Butcherblock, LGuk, Bugs & bats, Stone Spider/LDCs, and Efreeti Lord area in Sol B, etc) but that was more due to technical issues. The polygon counts in Kunark zones was a bit ambitious for the time so lots of people lagged horribly due to trees and such. They had to patch to fix those issues within the first month. By that time, you already had over half a dozen 60s (Elduran, Nevyn, Furor, Thogg, Thott, Hobben, etc).
- No new classes, since the existing ones don't all have a distinct role. There used to be a phrase used by the old (original) dev team called 'compelling reason'. The question they always asked was, "What's the compelling reason to choose this item/class/spell/race over any other?" Of course, that info was given by Gordon "Abashi" Wrinn (who was full of **** much of the time) so I guess it should be taken with a lick (not a grain) of salt. Personally, I can't stand beastlords (nothing against the people who play them, I just dislike the class) so opening them up to more races wouldn't affect or bother me at all.
- New player character models. Ones that aren't based on the Drakkin (who are goofily animated. And that's being nice about it) and that don't suck. Someone with some power over there should look at the TBS siren model. THAT model is well designed and animated. The Drakkin model looks like a teenager after a 10+ inch growth spurt: gangly, awkward, and totally off balance. Mind you, my only 85 up to now is a Drakkin so I've had plenty of opportunity to watch how the model looks and animates (I play in 3rd person most of the time). Heck, contract the SOGA people and outsource it to them or put EQ2's art/animations team on it since it seems farming out people between projects is the thing to do at SOE nowadays (a third of EQ's dev team is working on FreeRealms).
And that's just off the top of my head.
