Over the years I've tried to convince some friends to play this game, and one of the most common criticisms from a new player experience is the default UI setup, especially the amount of alerts that pop up.
It's very distracting and quite frankly seizure inducing to have every alert enabled by default. Considering new players tend to start during season, it's common to see hundreds of flashing notifications about successful or failed Tuvala upgrades, guild Wars, loot box results, rare item drops, marketplace notifications worth several billions of silver... It floods a large portion of the screen to an already complex game and is very obnoxious.
So my suggestion is: please disable every default alert for a new game installation. Players can always enable the back if they want to, but most players I know keep them disabled.
