Some basic suggestions

[London]

Herblore Supplies:
have herbs and secondaries drop in noted form from bosses in fair amounts, not sold in shops.

You can buy them from the store and they are relatively cheap - remember, we are trying to sink cash.

Superior Slayer Monsters:
Increase the chance of getting one, I'm almost 99 slayer and had TWO all up, Increase the chance of getting SLAYER monsters assigned in tasks.

RNG. I had 4 superiors in one task and then went on 5 tasks dry before. It's balanced and you shouldn't expect to get them.

Promoting Raids:
Only a small majority of players know how to raid, Give people incentives to take new players in (Like a slightly higher loot drop for a party with low KC)

People would alt-abuse the shit out of this.

Noted supplies:
More noted supplies from PvM (namely Zulrah, getting drops like "20 coconuts" is just shit.)

It follows the same table as osrs which is why it's like that but yeah, it's useless to have coconuts and no use for them.

Skilling Incentives:
Daily bonus XP to certain skills, Changes to a random skill each day.

Palidino has already said he isn't with the idea of dailies.

Runecrafting EXP:
Please buff RC experience, The skill is painful enough without having lower rates than other skills.

No, all rates should be kept the same. If you don't want to grind it then boo hoo.

Slayer Points:
Can we get more uses for regular slayer points? RoW Charging is quite cheap.

Suggest some, this point is useless without giving him ideas.

Seeds:
Can we get some use for seeds until the farming update? Such as trading in a seed for 10x herb of that type.

Good idea, should allow Bob to exchange them, through a custom interface.

Runecrafting is 50% faster than agility if you do it efficiently and without being a bitch. Deaths cap out at 3m xp/h.

This is true. You can get 1.8m to 2.2m if you're going at a steady pace, for rc that's good.
