Gem Usage

[Kruize]

Using them to speed up cooldowns in 1hr 59min blocks, don't speed up a 2hr 30min timer for 2 gems when you can wait 31mins. (Good use of gems)
Early game 10 gems for 900k credits/1.8mil+ coins. (Good use of gems) Shrine becomes more cost effective then the fair as you get further into the game.
Opening up chip slots in gear as you need them (Good use of gems)

Buying stars (Bad use of gems) Stars you get from the guild chests will be all you really need, as stars provide next to no benefits, they are just power inflators.

I didn't know stars were a bad investment. I thought the 3 basic stats has a huge impact on a hero's performance. Anyone can develop a bit more on the stars and their real impact on a hero?

I wouldn't say a huge impact unless you can get to the 7 star and 9 star+ stages, but they do have some impact even at 4. I think it's a good idea to invest in them some but not to go overboard. Kruize also mentioned guild chests, but most do not invest too heavily in those unless they can do decent and grand investments to compensate.

From my calculations 9 stars is equal to about a level 5 chip per stat. So 5 x level 5 chips for 9 stars. (4 x for mages since they cant use phy and skill attacks).
So maybe a level 4 chip equivalent for 5 stars.

Definately not worth the gem cost investment.

Is the power added a fixed power or a power that's affected by level? If a hero level 1 gains 9 stars, is the bonus better for a hero level 70 with 9 stars, or is it the same? I'm saying this because you mention a fixed increase in power (level 5 chip).

My intuition tells me that the power added by stars is greater as the heroes gain levels.
