I don't usually hunt for shinies and if I don't get one, I rarely worry about it. I don't mind them, but the true motivation to play a lot is usually something else, like the stardust bonus we have now.
Funny that you mention Swablu because it's the one shiny that I've randomly gotten the most. In total I've caught 11, 3 of which were from Safari with a boosted chance and 8 of which were completely random wild catches.
