Hello,
I've noticed while doing achievement diaries its a little unbalanced for the skill levels needed for the tiers that the task is on. To build the preface to what I'm about to suggest here's my mentality
behind it. Easy tasks are meant to be able to be done very quickly and early in, medium for someone who's like 750-1250 total, hard for people not quite at end game but not quite a noob and probably have 1500-1750 total. Then of course elite is for end game players with total levels around or above 2k.
My suggestions:
Kourend hard task- chop 100 redwood logs, moved to elite. explanation: 90 wc for a hard task is just too high.
western provinces hard task- complete a smoke devil task, moved to elite or removed. explanation: 1) its 93 slayer, 2) thermonuclear smoke devil is already a task in elite. its basically the same thing.
Varrock easy task-buy a starter home, moved to medium/hard or removed or reduce price of home. Explanation: i play realism, my first 10m took a while to get and i did not want to blow it all on buying a starter home. and it seems a bit unbalanced to spend 10m on an easy task.
