I specifically mean champion, but noticed the same thing on legend-only on legend it varies dependent on how much unavoidable elites you get along the way.
This also happens on Into the nest - bridge,ammo box by grim entrance,scripted event,before entering the 3rd tome area,just after or near the exit of 3rd tome area,then there’s usually a boss, then a horde right before you drop down at the area of no return, then a horde when or after you ascend, and finally the boss- same thing is with every other map.
I won’t write it step by step for every each one, but I definitely could.
I started playing on veteran and it’s the same on champion and now when I upped to legend it’s also the same. I get it that a horde has to come EVENTUALLY, but I’d rather be hit by a horde at the very beginning of the map sometimes to add some variety at least.
Also, I don’t get why, during scripted events such as warcamp battering ram escort we get spawns in the exact same places.(berserkers to the right between 3rd and 4th tent, then chaos with shields next to the last tent on the right and then a globadier also from the right) I mean,would it be that hard to just make them spawn but in different places? I get that on righteous stand it’s hard to spawn berserkers someplace other than the right or left gate(and even there I’m surprised they don’t pop out of the same gate every time) but during other scripted events there’s plenty of places to spawn specials/elites. By this point I do warcamp automatically and the battering ram escort is the most boring part of it. The horde is small,the event is scripted so hard that you always know where to look…If I play it any more I will be able to literally play it with my eyes closed.
