...more archers using self combos?

I'm new to the game, been playing for about 2 weeks. My son and I play together, and we started out with chanters. We pretty quickly learned that if you cast the level 12 ice AE and follow it up immediately with the level 10 fire AE, you get a combo on every mob around in you range. I would run in and drop my combo, he'd run in and drop his, and most everything would be dead.

So our thoughts turned to...how do we capitalize on staying alive with gazillions of mobs around us to combo on? Answer: Paladins. So we respecced and rocked it hard for days, had a great time with it.

Then came time for a change. We rolled Birds and went about looking for the combo. Took us a day, but we figured out that the two screams chained together followed by the AE attack (level 6 skill i think?) resulted in a solo combo. 3 skills instead of the two that it takes with the chanter, but not that big a deal.

Problem was, we couldn't get it to repeat often with bowbirds until we figured out that only the mobs who are affected by *both* screams get the combo on them. Answer to that? Get into melee range to unleash the chain of three skills resulting in the combo.

The result? We're both rocking dagger birds, pure dex, wing shields...pretty high survivability, and incredibly awesome damage, especially combined with the combos every 13 seconds.

So why is it that when we group up with others, we are the only archers we ever see doing their own combos? I know we didn't come across anything particularly new here...so why not? Why is it that all of the threads out there about the differences between bows and daggers (and talons for that matter) never mention that using a dagger means that you can combo more mobs every time you drop it?

Does no one care about combos?

TLDR; I combo, most people don't, I don't know why, /cry please feed me info on why they suck and I rock!
