Some waves in monster are easier than others, I remember one where the 1 monster was easy as pie compared to the other ones, but the first two rounds made them run for the exit instead of tangling with it. Best mental breakdown I've caused ever. Fight or Flight! Fight or Flight!
...
... a lot of people chose flight.
And as for easy on Snipers, a lot of monsters are, no matter which one you choose. The ones that have Pneuma? They move and can still be attacked, you can even move traps with arrow shower attack them that way. A sniper generally has a way to sneak by most monsters and killing it at the same time.
That's the reason I generally make custom monsters and add in ways to close the gap, or make the sniper in question need to think "Can I kill it?" instead of the usual "Yeah I got this" followed by the occasional, depending on the monster, thought of "Better run".
That thought of doubt, that unknown variable in what a custom monster might do when rude attacked is very amusing for me to see when the 5's and 0's start arranging themselves.
Though the Tae Kwon Dimik's were just funny, and the Undead Vesper with the Holy Cross was always a good time.
20k damage on ED users, hilarious
