The first two are true, at least before 88 summoning. But warped terrorbirds, you talk as if you have never even done a task. While cannoning these using a combat familiar I can return PROFIT covering both the prayer pots, super sets, and the cannonballs. They also come up to 50k+ slay xp/hour if you cannon. Please explain to me how they don't have good drops if you profit while cannoning, how they have rubbish XP if they are one of the fastest tasks with a cannon. It's true you cannot block all of their attacks, but by praying range you won't even need food because of the obscene amount of gnome foods they drop.
