Play the Templar, when you want to be a tank and support player for your group
Play the Gladiator when you want to deal damage and PvP as melee class.
I dont get it why ppl are actually all saying and asking the same. Play the class you want to play. This stuff about "I play only the class that is better!". Compared to WHAT? To WHAT? Gladiator and Templar have TWO TOTALLY different kinds of game play. So how to compare them beeing "better"?
Make the choice of your own abilities and interests and be happy with the result. And if not... reroll and play the other class.
Honestly I think you misinterpreted me. I'm not saying I want an iWin class in PvP and PvE, I'm saying that because of the PvPvE system that Aion has I am confused as to what would suit my playstyle more, hence me asking for advice.
I know they both have totally different styles of play, I know a Templar won't be the nr.1 ''zomg 1shot button'' class in PvP, but I didn't know there damage wasn't as gimped as say WoW's protection warrior.
Gladiators also appealed greatly to me because even though I'm not -that- fond of DPS'ing, 2 handed DPS is something I've always had a weak spot for and enjoyed, but in the end I enjoy tanking more, and that made Gladiators a viable choice for me because I heard they could tank too, I just didn't know they really were more of a 2nd rate tank than anything else. I can already forebode that ''the community'' will not be picking Gladiators to tank instances for them given the choice.
Anyway, thanks everyone for all the input =) I've made up my mind in that I'm going to be playing a Templar. I'll probably end up leveling a Gladiator as an alt later on orso, but Templar will be my main =)
