Realistic things you would like to to see in RoS..

More filters for combat. Example the ability to filter heals.

Weapon augs with both +damge & stats like in days of old.

Lots of new quests/missions.

You're a little late

Cows.

SHEEP!!!!

Toasters. Because once bread becomes toast, it can never be bread again.

It's probably a bit late being as BETA on Weds, but...

How about Monks fixed?

Casters doing half decent melee combat as once they have run out of mana they have sod all else to do.

In the same line of thought... Escalators are the only piece of machinery that can't break down, they just become stairs!

What good will clerics be if we have someone better at cooking bread?

AOE Act of valor

Enchanters can now direct their charm pets to attack a specific player when charm breaks.
Note** If a tank is targeted, the charm pet will automatically move behind the targeted player.

The OP said "realistic"... that right there would be a pipe dream come true.

I guess I really just want more content, and that T3 has fairly challenging group content. I'll be a little disappointed if I don't have to gear up and try-hard to progress through the content.

Every group named and raid has a DPS check.

Melee doing half decent caster combat as once they have run out of endurance they have sod all else to do.

Bigger and more advanced guild banks.

And strawberry rhubarb pie.

Group level augs that make your epic . Find lets just say 5 pieces, combine them and it makes a amazing aug (kinda like we saw in TBM.) Then make one for raiders from raid events, probably just 1 piece like the element from EoK raids.... you have to do both to get full powah, IE the augs stack on the weapon.

Archery should be allowed to land up to point blank, like all spells and melee...

Warriors should get a very short distance summon!

Other MMOs have lots of quests besides those for progression. It would be nice to do quests for fun rather than just necessity.

Quests for cool items instead of just progression.

Make quests that give actual rewards - making you want to do them.

I would like to see group size increased to 7 or maybe even 8. For me it would mean I can start a 7th account.
Also, new player race(s), new Epic quest for a 3.0 and an alternate fix to get the 2.5.
