Exactly. If you look in the patch notes, you will see that it still states the following:
The Update version 3.5:
Here it is:
- Once a Hero Class is unlocked, and set as the current Class, players can start to earn Champion levels, by using the hero in a battle. Champion XP is only earned if hero is used in battle, and for the current class equipped with the hero.
- Quests, Challenges & Explores give 1 XP to Champion Levels, all other battles (PvP, Arena, Events like Raid Boss) will give 2 XP.
- At milestone Champion Levels, the player will unlock the ability to choose a Talent from 1 of 3 Talent Trees of a Hero Class. Milestone levels are 1, 5, 10, 20, 40, 70, and 100.
- Perks have been removed from classes with the introduction of Talent Trees and Weapon levelling. However, the class weapon is still unlocked by winning 250 victories with the hero class (the Hero does not have to be part of the team for these victories to count towards the weapon).
- Classes now grant the troop type bonus when the class is unlocked.
They took out a feature that was included in the 3.5 Update to include and justify the cost removal of classes in 4.2.5 Update:
Relevant:
- Quests, Challenges & Explores give 1 XP to Champion Levels, all other battles (PvP, Arena, Events like Raid Boss) will give 2 XP.
As you can see, the Update 4.2.5 no longer have it:
- Hero Class change Gem cost has now been removed
- Players are now able to set a Hero Class to each team
- Hero Classes can now be managed from the Troop/ Collectible menu
- Class wins (for unlocking Class Weapons) will only apply to the Class assigned to the team
- Class Champion XP will only apply to the Class assigned to the team that is used (if the Hero is used on the team)
- A Hero Class still uses the same talent tree, so while you may use a Class on 2 teams, any changes to the Talent Tree with affect both teams
- The Hero Class displayed on the main HUD will represent the Hero Class attached to the last team you used
- As Classes do not apply in Arena, no Champion XP or Wins for a Class will be awarded.
Relevant:
- As Classes do not apply in Arena, no Champion XP or Wins for a Class will be awarded.
Again, while I agree that the Update 4.2.5 is good otherwise, they took out a feature that was introduced in the 3.5 Update. If this trend continues, and it appears that it will, then the future of this game is uncertain at best.
