figured that at level 45 currently, each quest is like 4k each, each mob is 550 each, takes me like 2 minutes to get up to that in grinding mobs easy.

You are grinding during quests... You just get a small reward after grinding. (Quest xp)

And grinding is boring..

Yea im gunna quest but kill everything I see, seems to have treated me well, 3 boe blues and a boe epic last night.

Yah, that's usually my route - Kill everything in sight to keep Xp/hour up during questing.

I like to grind/quest and queue for warfronts at the same time

Questing is better because ur gonna grind for the quest neway. What i do is leave all my quests complete, grind for a while then go to town and turn them all in to watch the exp skyrocket
Rinse and repeate. Works pretty well, have 3 level 50's so far working on my fourth

bull shit, s/s that or ur bullshit, you must have no fucking life then....

that's like 7 days played time in about a month now.

Depending on your class, simply AoEing down mobs can be faster than questing. Obviously you're going to make a good amount of money too.
