Crusader,Warlock or none?

Good morning mummies,
today i woke up with a very important question in my mind ( and it's really small,so i need help to free space )
With the last part of the patch the new troops have finally arrived and i'd like to ask you what you think is better:
switch to crusaders, invest in warlocks, or save the old and reliable angels and knights, considered that they already are at a good level?
Have a nice day

orome ... new troops are better than old ones
..... keep curent ones till templars/warlocks have a good lvl to use

Well I didn't see anyone using Warlocks so far, that should be considered.

Basicly for Mages and Archers there is no choice, Templars are superior.
We need all the tankiness from our minions we can get.

Ive seen the warlocks in a fight , they are kinda weak , and the mass skill activates really rare and the damage is reduced 80%, but still its on all units .

To the people who think they are better at Bosses , well they have bigger M def , but the HP is a lot weaker, and the special skill , the splash dmg , sucks against single targets.
