I've been 4x40 for awhile now, and thought I'd throw out some ideas.
Once you hit 3x40 or 4x40, most classes don't give you anything of value other than being filler levels, with the exception of a skill or spell here or there. The amount of power increase is just painfully slow. You end up bogged down for months with your abilities not really changing at all. If I get a level a week, which is about 1b xp for upper levels for those classes, it takes me 2.5 months to get 10 levels, and in that time, levels 31-40 of a class might give me 1 stat or skill that improves my character's solo or group power - and that will slow down as I reach the upper levels of 5x40 to less than a level a week.
Can we level avatar levels sooner? Most of our increased power will come from avatar spells and skills, but getting to that power is completely draining. Seeing how many levels Zuzu has on me, then seeing he's only av 15 is disheartening.
Is kill history increasing the diversity of areas that are being hit? If it isn't, all it's doing is slowing down levels, and levels are painfully slow as it is. I haven't spent too much time playing around in the the areas that just had xp bumped, but before this happened, even with the kill history, the good xp areas were the only ones worth hanging out in. As many areas as the mud has, there aren't a lot of areas where the xp is 75% of my favorite areas, making it worth my time to head out and run a new area once kill history kicks in.
We tried to 4 man chop last night, and we could only kill 1 town mob or 1 maw at a time. Part of this is because we don't have the avatar attack, most of us didn't have haste, few people have damn, etc, but we were a good group (Katie, me, Zuzu, Acme), and it wasn't even close to being worth our time. That used to be THE way to gain xp for avatars.
I know this is more of a personal thing, but can oghams be changed to the caster + 1 other like song of the mist? It's annoying to be soloing and have to take point, and if I'm in a chat group and soloing, I can't use oghams at all.
