Is it accessible: yes
Are there designs that make it harder for whales to instantly access everything: yes. Right now whales can only convert every 28 days.
Is it easily accessible: no
I disagree. I’d rather the scaling be changed though. Since we only need a say 5 troops at most in each element, we don’t need it to be as easy as leveling legendary heroes. It definitely can be made easier and the planned changes are a small step towards that.
There are 10 different legendary troops, but none like wizard or ninja or styx troops. Each troop has 2 classes so there are ten combos. They all have the same stat parameters (attack, defense, health, mana), but slightly different stat bonuses.
To your concern, if you convert a magic troop or a mana troop or a crit troop it’s all the same for conversions sake.
I disagree this makes styx and magic troops useless. Fully leveled magic troops will provide a larger mana boost. You can hit mana break points earlier at earlier levels (theyre real value) which means you save all of the food and xp with leveling.
I don’t see why it turns those troops useless? I plan to continue to use mine.
