Totally. Especially when some imbecile whispers you for food and drink in Stormwind. Charging them 20 gold each 1 food/drink gets them to go away, or they answer to Frosty the Water Elemental and my Gnome Mage.
That's just one button for a stack with a little mana as an expense.
Ye olde days I got at least 10 whispers a day "WILL U SUMON ME PL0X U R WARLOK U CN SUMON ME! PL0X!" which required me to get two party members and use a soul shard which was a nuisance to get because lock DoTs sucked monkey ass back then(they got buffed to hell and back in BC though).
In case I said yes, the two party members would be required to simply right click on the channeled portal then do nothing else, if they interrupted, I'd lose a shard and the guy wouldn't get summoned.
Most of the time people didn't understand the concept of "right click the portal, then do NOTHING ELSE" and it'd be 5 something shards before the guy got summoned and 3 whispers of "Y U SUMON SO SLOW?"
I'm glad WoW caused me to grow a spine for these things, a friggin online game made me grow a spine for social nuisances.
Nowdays it's
"Will u summon plz"
Me: Riveting tale chap.
"wut? what are you talking about, just summon don't be asshole"
Me: Ah yes in the old years I remember valiant battles of yore, I wish I had gone down along with my companions instead of retiring into a rot of boredom and booze(didn't type this everytime, just a macro lol).
"wtf are u saying ur not making sense"
Me: Why marvelous, this teacup has just the right amount of sugar and goes well with my monocle.
"okay wutever I get summon from sum1 else".
I can imagine though the food/water whispers can get annoying after a while since people need them
much more often.
Playing a Hunter now though, I really wish I could have the cat in my avatar as my pet.
EDIT:Wow leveling as a hunter is ridiculously easy...just..wow, didn't think anything could be easier than a Deaf Knight.
