Did I make a mistake by choosing to play wizard?

[Belleraphone]

see title. I was attracted to their high burst damage but after browsing the forum it seems people think pretty lowly of wizards. Could some of the more experienced players offer some clarification on this? Should I reroll? I'm fine with being useless for my low and middle levels, but I'd at least like to be useful at the higher end/raid type stuff. Seems like the general consensus here is that even when wizards are useful, someone else can do it better.
