What it was said is interesting.
You might speak really well, grammatically, on the other hand you might not speak naturally because of your accent.
I believe we've got to know where to put an stress on words when we're speaking, otherwise it won't never sounds
how it should be. I've got a Brazilian teacher, and this classes of her are taught in English.
Sometimes I can't understand her, because of that terrible Brazilian accent ! I get crossed everytime I've got to spend a couple of minutes figuring out what she's said.
Lose the accent, in my opinion it's important, but I think there's always going to be at least a bit of accent for a non-native speaker which is just fine, but not much otherwise is difficult to have a proper communication.
All in all is even cute to listen to someone speaking English with French accent or ,I don't know perhaps Italian accent but Brazilian accent just doesn't please me rsrsr, perhaps because I'm Brazilian
