Do bonus stats affect your character choice?

Nope

Same like me.
Step by step this will be a looooooooong journey. Leveling up all bonus stats but encouraging frequent change of characters hence avoiding boredom.

Yeah. Lately I am somewhat avoiding Health regeneration cap characters.

These include most infiltrators and adepts.

They make game too simple anyway... it`s good to avoid them a bit.

I just pick a kit that I´m in the mood to play.

An additional 1-5% of shields can still make the difference between going down or staying alive. 

I play the characters I find enjoyable. The bonus stats are so minute, that they won't make too much of an impact regardless. Let's hope they keep it that way too.

There is no joke, there is no poll. Is this even BSN anymore?

5% power recharge makes difference. There can be no argument.

Mine is  currently at lvl 3. All my bonus stats are at high level 2 or low lvl 3 except health regenration cap which is at 4 for me playing adept and infiltrator during early time of MEAMP.

I am trying to play at least one or two games a day using Angara Insurgent, Asari Huntress or Salarian Operator to get power recharge level up to 5 eventually.

Doesn't impact my choice much. But if I notice a stat is close to levelling up from my usual "play what feels fun" approach, I might be a bit more inclined to pick a character with that stat.

First off, only slightly, when I get really close to a stat I finish it off.
The cost scales like this... to get bonus rank 1 takes value x, to then reach rank 2 you need 2x, to then reach rank 3 you need 3x... and so on.  I'm assuming the trends will continue.

In terms of character power, health and shield strength are separate entities that add up to your total bullet sponge factor.  Together they provide 10% effective health.
Health regen cap % is nearly pointless is most matches, rarely being relevant (since medigel/being rezzed/wave ending all put you over your cap).
Shield recharge delay is extremely useful however, especially for characters that don't have the "50 DR, 100% regen delay while in cover".
Recharge speed is also very useful, but many kits use powercells or have large recharge speed CD bonuses already.  If you have 100% recharge speed already, then another 10% really acts like 5% would on a talent-less character.

Basically, each of the bonus stats are depreciated in some ways to be worth less than "10% character strength" due to diminishing returns and the fact that there are situations where they don't help.  I would arbitrarily say your character is 20% stronger with max bonus stats.

Well, I'm doing it mostly to complete the challenge, but I think it is sill more useful than 6% more shields or 6% Health regen cap.

Don't need to promote. You still get exp towards bonus stats on level 20 chars.
