They kinda do. Run TC20, no $$ cost to you and you get them in return for some resources you donāt have to pay $$ for.
I donāt really know what to suggest beyond running TC20, 5% odds for a 5* hero according to the data trackers.
You will eventually have a solid SI roster, the more TC20s you run the sooner that happens. The tradeoff is fewer feeders and slower leveling, but when not paying cash you pay with your time.
Feel free to contribute something positive of your own. A strategy guide for using a restricted bench of SI heroes for example. I am sure it would be appreciated by some players in your situation and you may find a kindred soul that shares ideas with you.
I was just trying to be helpful in giving suggestions, it was not a complete reference to every hero in the game. 4* didnāt get a mention either, that doesnāt mean they are not relevant, they work even against SIII heroes in formation (I know, I brought Proteus and he helped win a raid vs +20 5*, a mix of Ninjas, Atlantis and SIII).
The idea is to spur people to think of options, strategies, synergies, etc since that is one of the key, appealing aspects of the game.
Really donāt feel there is a need to get snippy with others trying to offer something up and be helpful. Sorry you donāt have all the shiny toys, I donāt either and I also get annihilated from time to time
