Hello!
If the game is going to be tab targetting style, I was wondering how you guys planned to design the spell casts.
I've always thought that something could be added to the standard casting mechanic to prevent the player from sitting still and bored spamming buttons.
For example, you can choose the time you want to charge a spell (or some powerful melee attack) within a minimum and a maximum time determined by different casting bars.
For example, a magician who throws a fireball can cast a first bar of 1sec. and release a fireball that deals damage or keep casting for a second additional 1sec cast bar (1sec + 1sec = 2sec total cast) to launch a more powerful fireball that can apply burn.
I also find it interesting to add the possibility of casting while moving but applying some disadvantage to it, such as that you can only move at 50% speed while casting and also, cast times are increased while in motion (this would simulate that while in motion you lose focus on formulating the spell).
PS: sorry about my english.
Nice ideas there, sitting still while casting is a bit boring for sure, and I think that it can be done to move and cast, but to have consequences if you do that.
For the "powering up" spell, it's interesting for sure.
