1.) ability to trade in marks of grace for agility xp? maybe 500-1k xp per mark of grace? after you have a graceful set there's really not much use to keeping the marks, especially now that you have a chance of getting some amylase while doing the courses
2.) add coal bag
3.) add daily objectives? complete all 3 (or however many) for a random clue scroll, xp lamp (for non-combat skills), a free boss task skip scroll, etc. not sure on the prizes, but there's a ton of opportunities for the objectives
4.) absorption pots don't work in MA2
5.) implement this: Certain items (mostly limited to rare monster drops) can be exchanged for x currency based on OSRS GE value, similiar to how coins are exchanged 1K to 1 for platinum tokens.
from the original post about rares/plat tokens, maybe at a set rate per item that is slightly below market value so players will still attempt to sell the items to players before exchanging. ex. an item worth 10m will exchange for 8k-9k tokens rather than the 10k you'd get from exchanging coins. alternatively, maybe a shop for buying the items for coins for the same exchange rate above, for getting rid of item drops accumulated that don't sell often
6.) option in the GE screen that shows you the average price of the last 5 transactions for that item. ex. last 5 ags sold for 50m, 60m, 60m, 55m, 70m it'd say "Recent Average Price: 59m" or something to that effect. a lot of people over-sell in GE and it creates a lot of dispute about prices pretty much daily. this would help newer players with prices and it would clarify prices in general for everyone
7.) ability to trade emblems for gp or blood money, would give more players initiative to PK.
8.) add bar box/herb box/etc. to pest control rewards
9.) cash rewards for clan wars tourney aren't what they say they are in the menu. also, if you play on full screen the countdown when in the match (the 1 min. grace period) is partially covered up by the map orb.
10.) xp drops in the clan wars tourney? normal accounts can set their stats anyhow, the xp drops would aid in timing for specs/ko weapons
11.) when you leave a clan wars tourney you have to relog to reset HP. it stays at the level that the tourney was set to, and if you use the pool/eat food to heal it doesn't. you need to relog to be able to restore HP
12.) if nobody is in a bank/shop screen inside the clan wars lobby, skip the extra 1 minute to look over items. if someone is in a bank/shop screen, the extra minute would be given
all i can think of for right now, if i think of more i'll edit. constructive criticism?
