Yeah, templar abilities are quite known too. We have only 3 + focus (which is a mistery anyways).
- Blessed blade, it seems to be a buff yes. I hope it has a nice effect, so it doesnt feel like a passive that takes 1 slot ¬¬
- An icon which must be a dispel effect like in DA2 for the icon, surely around the templar so it is different from the dispel spell of spirit. We will not know how good it is until we play the game. But judging from previous ones, dispel is always always a good thing!
- Holy Smile or whatever it is called finally, which is an AoE around the templar, damage and stun, we saw Iron Bull use it in that choke point just before going crazy spin to win. Crazy fun ability 
The passives will mostly be antimage and stuff, some magic resistance, interruptions, etc. I hope they manage to invent some nice and original passives!
I am really tempted to play a 2h Templar. Cassandra can stay home, Im totally banging Josy, she is just too cute.
That's alright, Cassandra can hang out with my necromancer

Yeah i agree with you on all the Templar info. I too considered a templar given the human backgrounds relations to the chantry, but have fallen in love with the whole idea of the tempest specialisation.
Im currently considering who my tempest will be.. dwarf, qunari or human.
When i saw the flask of fire ability in the video ....i got pretty excited. Possibly imagining sera bursting into flame haha.
I mostly play mages, however tempest has gotten me interested. Mostly cause i think if i wasn't a mage in thedas, what would i do/ use? Im a bit wary of lyrium addiction ....
If i was a mage, id like to be a spirit medium or a battle mage type of character, hence my interest in Knight enchanter and Necromancer.
