Bertram made some really good creatures stats table that will allow us to tweak their stats, this opens lot of options to specialize some creatures and give them special behaviours; ill try to flesh out a initial creatures stats, Tiers and roles. (a few creatures are not included yet but planned (*), at least for evil side so ill just put down the most important ones, refer to viewtopic.php?f=35&t=5604 for more info)
I would only use small integers for the values since they are more explicit and easier to handle than floating ones.
Roles: creatures can be
Balanced
Tanker
Damage dealer (Damager on short)
Ranged
Support
Tiers: creatures can be split into four tiers, its an indicator of their power. Each tier has relatively similar stats values;
(ordered in ascending power)
Tier 1: Weak creatures used at start of level (or early campaign levels), low room requisites
Cave hornet - balanced; weak, used as scout, flies
*Roach - balanced, hp above average
Spider - Damager
Tentacle/s - balanced, good on water
*Swamp pup - Damager, good on water, future ranged abilities with skills
Slime - Tanker - good hp, magic only damage (acid), high Physical def, low magical def
Goblin - Damager, combined stats are overall better than the others, the king of the low tier
------ Hero side-------
*Dwarf miner - Support, weak but he can dig
*Fae dragon - balanced; weak, flies, used as scout, future ranged abilities with skills
Halfling - balanced, to substitute the gnome
*Dwarfzerker - Damager, low def (any of the dwarfs 1/2)
Adventurer - Balanced, good stats, but its many skills are his real weapon, the king of the hero low tier
Tier 2: Average strength units, the barebone of your army.
*Skeleton - Balanced, weak, doesnt sleep (only when healing) or eat and is cheap
Robominer - Tanker, as a special unit that only appears on some levels, digs really well, but cant claim or enter water/lava
Wyvern - Damager, high speed, flies
*Cultist - Support, healing, buff and debuff skills, your main mysthic worker, also decent researcher, average-low stats, magical damage
*Warlock - ranged, researcher, average-low stats, high magical damage
Lizarman - balanced, fast speed
Orc - Tanker, good physical damage
Kreatur - Balanced, the king of his tier
------ Hero side-------
Knight - Tanker, high hp and physical def (its sad how few heroes models we have)
Tier 3: Strong units, expensive, but they are worth it
Scarab - Damager, very good stats
Troll - Tanker/Damager, best physical defense, decent magical def
Dragon - Damager/Tanker, high physical and magical damage, good physical and magical defense
------ Hero side-------
DwarfSmith - Tank, Slow but good Hp, good Phy/Mag def and dual phy/mag damage dealer (Dwarf 3), blacksmith ability
Tier 4: The strongest, most exigent and difficult to manage
Pitdemon
------ Hero side-------
BigKnight (I would call him king)
