If you have the money, you could train slayer with a cannon and get some extra xp in the slayer category. Also, cannons are extremely fast as they shoot rapidly and hit higher than most people can with even the best bows.
F2p or p2p? THere are totally different things to merchant for whatever you are. If f2p, pretty much the ONLY thing you can merchant for good money is god armor, and p2p has a wide range... just pick something that isnt overdone, buy cheap, and sell higher.
Maybe it is a hidden update so that people cannot go to other windows and just listen for when they are done woodcutting or whatever, or when a random event comes.
I think it's funny how people put hundreds of hours into Runescape when they could work a minimum wage job for 12 hours and buy Runescape for almost the whole year. So, why not get p2p? its just 5 dollars. That's less than the price of a movie ticket, and you get 30 days of fun instead of an hour and a half.
Averaging 5 hp per hit, it would take around 635k bronze arrows (without picking up) to 99 range. I would reccoment iron arrows, they are around the same price.
That's a really hard loss Jimmy, but you will get over it and still play rs and still have fun. Look at me... I have a net value of like 8 gp and this game is still awesome.
