Injustice Gear - a simple explanation

Note: I gleaned a lot from Rom Sudo's Gear Faq (I recommend looking at Rom's spreadsheet which shows best items & abilities as well).

Here's my take on Gear:

Get it:
Acquire gear by buying packs or placing well at the end of an online combat Season.  (Rom Sudo says you can get gear in online combat, but I never have.)

Inventory Quirk:
One piece of gear can only go to 1 character, even if you have 3 copies of it.  Extra copies should be shattered for Shards.

Rarity:
1-3 stars = rarity, best gear is 3 stars (apparently you can evolve 3 star gears to 4 stars).  1& 2 star gears have 2 abilities, but only 1 starts unlocked.   To access 2nd ability, you  have to level up  gear 10x, then Evolve it.  This costs a lot of $$ and Shards.
3 star gears are generally strong, and they have a 3rd bonus ability only for one specific character, and they are the only source of Purple Shards (required to Evolve gear) when shattered.

Gear abilities stack, ie 2x +5% block gears = +10%.

Gear abilities vary: boosts to Basic attacks, bonuses to blocking, bonuses to Special attacks. Evolved abilities seem stronger - bonuses chances to Crit, chance to Heal, chance to Life Drain, chances to Cancel or Reverse enemy Special Attacks.

I wrote this up because there's a 1/2 price sale on Gear Packs this weekend (end of Aug 2014) and I wanted to be clear about the mechanics of it myself.

Recommendations:
Skip gear if you have no Gold characters.  Golds are the gamechangers, Gear is not.  If you have a few Gold characters, maybe get some Gear for curiousity, but stil the best buy is the $75k gold pack or gather $400k for Red Son pack.  (I haven't been patient enough to do that yet.)

Gear will *NOT* decide a battle in favor of significantly weaker characters, but it could help a lot for evenly matched characters.

Social Media -- enough ROI for us, the users?

A European friend of mine earnestly opposes social media because the product being sold is *us*, and yet we the users lack almost all control over content and we gain little benefit.

I argued otherwise, saying that a shrewd user can gain significantly: expanded social network, keep in contact with people no longer nearby, gain insight into lives and careers of friends and acquaintances, and get entertained by the latest viral joke and media clip.

But as social media is deepening, privacy policies are becoming less protective, the NSA (and likely other governmental and non-govt groups) have gained access to our personal data for 'big data' research, algorithms can now identify us by metadata and facial recognition (and tag us without our consent), and hackers seek to manipulate us by stealing our information and identities for various mischief and crime...

It seems a particularly good time to ask, "Are we getting enough from social media sites in return for access to so much of our personal information?"

Any opinions? Anyone (not) afraid?

Anyone concerned about their social media getting hacked & getting framed for something?

Any recommended alternative sites?

Anyone know of class-action lawsuits in progress to reclaim our ownership & control of our data?
