Some of us were discussing this earlier.
Did SG stated this at any point?
If they did, they certainly didnāt live up to the promise (since they arenāt adding more HOTMs to the list as months go by). If they didnāt, I guess we can clarify that in the faq to avoid misunderstandings or false expectations.
They did and they have been adding to the poolā¦?
Took this screenshot this morningā¦ All hotms > 12 months old are in the pool.
Thanks for clarifying! Never thought they would add them myself.
And since I am not using HA10 myself (troops seem better to me, considering chances), I hadnāt noticed.
Someone was mentioning in LINE so many heroes were missing, but since they were speaking about event heroes and old HOTMS, maybe they only missed the event ones. 
Recommendations for the Hero Academy:
Retraining for Legendary heroes (5*) percentages:
Training for Rare (3*) and Epic (4*) heroes percentages:
Troops trainings cost for 1, 2 and 3 stars troops:
Training for 1* HĆ©roes elements:
Level 6 takes 2D and 12H though, unfortunately not just 2D
Thank you, I have updated it and @Guvnor I replaced the graphic a few posts up for you to use in the OP.
Ok, I am new to HA and being F2P, I was working long for HA 10.
But 7 days for a retrain, with 5% non-S1 heroes, So mathematically 1 non S1 heroes over 5 months.
Geez, Consider a year work on building and research work to make it workable, then recruits and food cost on top of it.
This retrain time is ridiculous, may be max 2 days, like TC 20. 5* chance from the ever growing hero list is too low.
I donāt know, but this just endless grind, unless few lucky retrain posted on social platform, getting 1 good hero will take years.
I feel you. But this is what this game is all about: grind, grind, grind. And a whole lot of patience.
costumes added to hero academy, thats goodā¦
but cmon its time to add non S1 and costumes to HA lvl 8 and lv5
we need a way to get free non s1 3* and 4*
i havent made it to that level yet, but i am wondering, if we retrain a 5* hero. what are the chances of getting something other that S1?
5% chance to get non-S1 heroes.
It is explained in the table also in the HA10 Details.
And it is also appeared in the game.
thank you @jinbatsu
i havent reached HA10 yet, but it is good to be prepared for it. in hopes that when i do get there, i will be able to received some cool heroes.
7 days!! set it up and forget about it 
can you please share with me the required mats as well?
1288k food, 300 recruits, and 1x 5* Hero.
The HA really needs to allows for three actions at a time instead of the two it caps you at right now. Iām running the rare troops and HA10 legendary retraining and have no chance to (probably ever) do any other action like the Trainer Hero one, which would be nice.
We need a revamp of HA
-allow 3 actions at same time instead of 2 currently
-chance for non S1 epic/rare in HA8 and HA5
Today I was very fortunate to pull at the H.A.10 the only one missing in my classic 5* heroes collection!
Every time the Costume Chamber gate opens, I only wished to get Leo!
I guess it was a perfect gift 
for my birthday weekend!
Now, the Spartan of my dreams came home!
I think every body getting the same hero. I am also got the same hero
I got this hero yesterday
Question. Will someone be able to train troops if ever you want to stop training trainer heroes and you still got some trainers to collect. Iām running out of sharpening stone, so want to restock on the item and focus on troops for now.
P.S
HA 10 is also in full retraining mode.
