Ive used 4 gear removal events and i started a year and 2 weeks ago .. gotta be on the lookout for when they happen since its really random.. but they do happen and more often than you think ... think we had 6 over the last 12 months .... 

They dont last very long , so dont miss them when they happen !

Ya this is the only game i ever played that essentially charges you energy to remove gear. Since silver costs energy, it's basically what it amounts to. Removing one 6-star piece costs in those terms about 32 energy in spider 20. FUUUUN !!!

a couple of thoughts:

- You should not regear all the time, but you should definitely do it when a champ would profit significantly. 500k silver is not much compared to the benefit you gain. Gear is half the power of your champs. Running lower dungeons than your account is capable of will very quickly run up to much more resources lost than a bit of regearing

- In some sense, the silver cost protects you. If it wasn't there, you'd feel pressured to swap around gear every time there was a tournament or something. When it costs silver, then the "casual" way of playing the game becomes identical to the optimal min-maxed way.

- I do agree that the cost is too high, though! It could easily be 1/2 and still fulfill the same role. I have the same complaint with masteries and blessings. Those swap costs could be cut by 90% and I still would mostly not touch that stuff.

I agree with your post a lot Urlibu, cost is just far too high for players.  Fun of this game is supposted to be building your characters, but with gear cost removal, most my toons will only ever be built once at least up this stage of game for me.

@xGhostwindx .... If you spend any money on the game, Forge Pass is great.  It increases you XP and Silver by up to 50%.  Monthly gem pack will give you enough gems to grind gear to sell and get  more silver.  

This game is about long term strategy.  We all have to make hard decisions.  Assess what you will gain by regearing a champ vs what resources you expend.  Often, you can upgrade one piece, destroy the old and make a difference.  

Summoners War also charges for gear change, but they also have one day every month when you can regear anyone for free. They've also added a new feature where you can buy a day of free re-gearing for a number of crystals.

More frequent gear changes would definitely be beneficial.  In my experience you spend less silver on regearing the further you progress.  Very rarely do I do full rebuilds of champs anymore.  Most of my silver expenditures come from rolling gear.
