Please don't do that.
Don't just dismiss an opinion you happen to disagree as if it was just childish, and product of hipster kids.
Like it or not, Lightning IS cool. Its one of the most visually impressive phenomenons in the world. Its what made viewers go "HOLY SHIT!" When the firebenders used it on Avatar, its what made Palpatine a memorable character (as well as his known quote on infinite power), its the main hook for shamans in wow, its the most visually impressive spell on skyrim, ect.
Then couple that with the fact that SWTOR has some really crappy-looking spells. Seriously, the heals look lame, the shadow-based attacks look like crap. Look at how in wow a Holy Pally can cast stuff like Light of Dawn, or Holy Light to heal you and it looks great. Then look at an op or trooper healing you and see how terrible it looks like. Inquisitors happen to have the one visual element that is actually impressive-looking, and its lighting. However Assassin's don't use it. They stab, not shock.
If you don't like lightning (and that's a very odd stance to take, as lightning is awesome) then that's your cup of tea, but please don't act all dismissive about it as if it was a child's play, because its not. Lightning is popular for damn good reasons, as is Fire.
