I’ve repeatedly said to so many individuals that you need to level your 4* heroes as a priority before you focus on 5* heroes, I’ll just make a post instead of being a broken record.
There are 4 main reasons you should focus on your 4* heroes first.
1.) you can max a 4* hero approximately twice as fast as a 5*, with half the expense.
2.) events and titans and wars are the main source of ascension materials. You won’t be very effective in wars with like a couple heroes who are partially leveled, same with titans, and the most important of these 3 is events. You can’t complete the epic category without having leveled 4* heroes. 5* aren’t allowed in epic, so you need leveled 4*. Incidentally 4* heroes can beat the legendary tier quite easily, now you’re earning guaranteed like 6 unfarmable mats a month from events. Don’t forget quests either.
3.) following the train of thought that you need 30 leveled heroes to be competitive in wars, you need options on your offensive line ups in raids. If you sink all your time and resources into 5* heroes before you even have like 3 teams of 4* heroes, you just won’t have options to play with in raids. A lot of newer players get frustrated raiding. I did too. That frustration stops as soon as you have options to choose from.
4.) a 4* hero at 4/70 is usually better than a 5* hero at 3/70. Since ascension materials are quite rare, use them wisely! With 4 hidden blades you can max boldtusk. It would take 8 hidden blades and 6 mystic rings and a tome of tactics and a Damascus blade to max a red 5*. Do boldtusk first, or Scarlett or whatever option you’re looking at for a 4* red instead of bringing azlar to 3/70. Your 4* will do much more for you in earning all the mats you need.
I know 5* heroes are cool, and everybody wants cool heroes. But it’s way cooler to have the ability to beat every aspect of the game, earning you ascension materials so that you can continue to improve your roster. It seems every newer player and some intermediate players get stuck in the trap of thinking well 5* heroes are better, and that becomes their focus. This game takes patience. Partially leveled 5* heroes without a solid bench of maxed 4* heroes is just the wrong way to play this game.
