Forgot to mention : There is literally no advantage in building "themed" decks (undead, bandits etc.). Mixing it up is way more powerful than the globals you might or might not have and get in time to be relevant.
The cpu is a cheating bitch btw.
But yeah, either go parting gift and spam cheap weak units or play wait and overrun em.
The legendary cards are mostly fluff, the most expansive are the most useless generally. Yes, there are some glaring balancing issues. 2/5
There is way too much focus on the resources. Every round plays the same: Wait for 4-5 Goldmines and at least 1 of every other resource, play some garbage cards to keep the cpu from your portal (discard half your hand because none of the 5 ore and crystal mines showed up so far), or don't and just use repair later. Wait until the cpu has a weak lineup/wasted all his good cards, fill all 5 slots with summons of choice, wait until you got ~300 gold, summon everything at once, victory.
2/5
The first world lasts way too long and is uninteresting.
The waiting time between spawns really gets annoying.
The music is repeatative and gets on your nerves really quick.
Is there any point in survival mode ? You stand arround waiting most of the time.
For the people who didn't find out yet :
You only have to build the cheapest elevator type, and only one per level. Just use one shaft to connect 2 levels, no more, noone will ever complain about elevators. Just be careful to no accidently try to build a new 2-lvl-shaft directly over an existing one, since it will just expand it.
You should build 1 or 2 staff elevators tho, can be one shaft connecting all the lvls, doesn't really matter.
After completing it with all 3 classes, i have to say you should rebalance the skills and the enemies, it really gets way too easy towards the end.
The fights are too short for the DoT and debuff skills to be worth it really, i think the longest battle was 4 rounds. When you put all your attribute points into your damage stat you can oneshot pretty much everything with one skill, you don't need defense when there isn't anyone left to attack you. The last boss dies while bludgeon stunned.
On another note : the last skill in the warriors rage tree (murder?) is pretty much useless, it does about ~40 dmg more than your autoattack at 100% stamina and uses up all of it. It might get better with a full willpower build, but then you are useless for the rest of the fight.
Pretty much the same with the +20% agi passive. You will hardly spend any points into agi to begin with, if any at all, so it's about +3 agi.
