Monsters Overview: 2 Stars/3 Stars monsters overview

Just thought that I should post a brief overview on some of the stronger units in the game. You don't even need all those fancy 4 and 5 star units if you take strong 2 and 3s and upgrade them. Here are a few examples which I have found:

The 3 Stars:
Eikolon Priests (mainly the water one) Grim Reapers, Fire Inugami, and Inferno are all very strong, and not too hard to get after a few 3-5 scrolls or extra crystals.

The 2 Stars:
Hellhounds and Warbears are very very strong when upgraded. The Wind Warbear is actually one of the only ways to beat someone with a water priest.

Eikolon Priests have very good support skills like aoe healing (all), aoe immunity (fire priest), and a 20% hp shield every time you're hit with a crit (water priest). Almost all dps monsters have high crit so this makes the priest invincible unless they can do 20% or more in one hit. and with full hp runes you can hit 20k hp on a maxed out priest.

Inferno and Grim Reapers are very good for their aoe damage, they help a lot in dungeons and have good dps for arenas.

Fire Inugami has a unique passive that lets him attack again after killing someone so he's very strong in the main storyline areas and it has strong dps.

Hellhounds have really good synergy, some have aoe damage buffs (usually after awakening) that really give you quick kills.

Warbears are very strong for being 2 stars, they dish out almost as much damage as dps classes, and are amongst the tankiest monsters in the game. Also, the Wind Warbear has a skill that unleashes all damage previously taken. I've hit up to 12k non crits with it. The Wind War Bear's main use is against the water priest because it has a low crit chance but high base damage.

There was a graph for 3 star monsters that had their rankings in order and i'll put that for everyone to see eventually, just have to find it again.
