Please consider the complaints of many, many of your player base to remove chemist soulstones from the guild tournament shop. And never add hero soulstones to this shop. Ever!
Unless there are radical changes to how coins can be earned, and the rates vastly improved, there is a giant imbalance between the costs of stones between this and any other shop.
Crusade shop allows roughly 25 soulstones to be purchased every day.
Guild shop rates can vary depending on guild, but most earn enough points to purchase at least 5 soulstones a day. (plus there has not been a new hero in this shop for many months, so many players have a large stockpile waiting to be used)
Arena shop is skill based and variable. The majority of players will be able to purchase at least 5 soulstones every day. The top rate is over 15 soulstones per 2 days. Very few heroes have been released to this shop recently too.
Grand arena has had many strong heroes released to this shop recently, and is the only one of the so far mentioned shops to contain orange 1/2 gears. The vast majority of players will be getting 15 soulstones every 2 days, or a gear anywhere between every 2 and 5 days. I am not one that complains about the constant stream of strong heroes released to this shop. Yes, it would be easier if they were placed elsewhere but overall they are still easily gotten and it is possible to compromise with your coins. You can still get soulstones every day while also saving some coins for a gear at least once a week.
Recap: crusade 25 ss/day, grand arena 7.5 ss/day or 1-2 gear/week, guild 5 ss/day with many players capable of much more, arena 5-7.5 ss/day.
Now you've added a hero to the tournament shop. This is the only place to buy red gear in the game. (Compared to o1/2 gears which can be purchased with grand arena coins, or gems in both troll merchant and godfather shops.) This will now also be the only place to get chemist soulstones apparently. IF a person is able to win every single bet over a tournament, they will get a maximum of 15 soulstones every 2 weeks.
You are asking us to choose between soulstones or red gear that are exclusively in one shop with a maximum rate of 1.07 soulstones/day with ZERO lost bets over that entire timeframe, the gear rate for the cheapest red gear I've seen is about 1 gear every 6 weeks (again, with ZERO lost bets).
I realize that chemist is a strong hero, but he is not a minimum 7.5 times better than any heroes in the grand arena shop which is considered the next hardest shop to obtain heroes from due to the sheer numbers of good heroes there and the limited rate they can be obtained.
At the current rates, a high VIP player that has gotten chemist through the magic stone chest already will take a minimum of 8 months to get him from 3 star to 5 stars. Those not fortunate enough to have him already will take a minimum of 11 months to go from 0 to 5 stars. Every single gear that gets purchased instead of soulstones will set back that clock a minimum of 6 more weeks, many gears up to 12 weeks or roughly 3 more months. Again, this is with absolutely no lost bets over this entire time frame.
This placement of a hero in the tournament shop is completely ridiculous. Please hear the voices of your player base and move chemist to another shop. You've asked your players to win around 88 bets in a row over the course of 11 months and not purchase a single piece of red gear over that time just for one single hero. Please, please, please reconsider.
