Unless I am using my defender, I prefer discipline and intellect. This is the breakdown. Discipline: 0% 1 minute cool down, 100% 27 second cooldown Strength: 0% 1 minute and 9 seconds, 100% 31 seconds Intellect: 0% 5 minutes 30 seconds, 100% 3 minutes and 55 seconds (This is assuming you kill no enemies) As intellect increases, the amount you get per kill also increases and reduces the cool down even more. From 0 - 100% you gain about 2 times more per kill. Hope that helps.

STR, INT, DIS all reduce the cooldowns of your special attacks. INT - Super cooldown. DIS - Grenade cooldown. STR - Special Melee cooldown. Depending on what abilities you use most, you can select armours and weapons that reduce the cooldown time of those particular abilities. Does this make more sense now?

the better question should be does Armor, Recovery, Agility matter? sure you can see Agility effect you but what about armor and recovery? or even you defense rating?

Check out my titans. I much prefer high intellect and discipline on titans. On my hunter, I find intellect and strength most necessary

YES, yes it does matter ...although imo it matters more in PvP than it does in PvP, but it matters nonetheless see, when i started playing PvP i would equip my "BEST" gear, i.e. highest light level, little did i know i couldn't possibly be more mistaken. of course i kept failing again and again, never getting enough kills, hardly ever had my super up,...i thought i was just THAT bad, but luckily for me, it was only a part of the problem then i realized the Gear actually has perks that COULD be useful let's take faster reload - see, i am a handcannon guy, so the other day i took a stopwatch and did an experiment. i equipped my Max Level gear, fired my Hawkmoon and reloaded and then did this again 19x more times while measuring how long it took and came to conclusion it was something around 3.5seconds (i don't remember exactly, but i believe i am close) then, i've equipped a Vendor gear with lower light level, but Fast Reload for Handcannons and did exactly the same thing, again, 20x. i was rather surprised when i realized it reloads in 2.5seconds, which is faster by roughly 30% ...once i realized this, i went further onto the stats, i know how i play and since i main Gunslinger in PvP, i knew exactly what i needed - MOAR Tripmine Grenades and MOAR Golden Gun. now, this one is much harder to measure, since it's not charged based on your perks alone, the KILLS is what you need more then stats, however - when i had my Max.Light gear equipped, averaging say 10 kills per match (i know, not impressive, however for this example it will be more than you might think), i noticed i could barely get my super charged once per match, ONCE so, i've changed my gear to one that has 100% on Intellect, and to my big surprise i charged my Super roughly twice as fast, so with the same amou nt of kills i would have it charged TWICE per match,....the other thing to notice tho is, that the more Super means (usually) more kills, and more kills mean again more Super ;) ...i am planning on testing this in PvE with a stopwatch again, but like i said, i don't think it will have much of a value for PvP, since the kills is what plays the biggest role when charging your super there [b]TL;DR[/b] - [i]the stats on your armor not only do matter, but they actually affect your gameplay (especially in PvP) in a [u]significant[/u] way[/i]

Equip gear with ONLY strength or discipline, but not both. So equip a full strength build with 0 in discipline, or vice versa. Then use your Melee and grenade abilities back to back, and watch the difference in how fast the two charge back up, you'll see a clear difference.
