I do my best with my writing, and I expect others to do the same. I try to give them helpful pointers. I'm not a "harsh concritter" anymore. I had my flaming days, and I'm thoroughly ashamed of them. I was unnecessarily cruel.
I'm not even going to bother trying to reply to the rest of that, I'm afraid. Give me examples of our "spotty grammar and sentence construction", particularly mine. I like to have my errors pointed out to me- that way I can improve.
I don't know how individual members react to concrit. I, personally, could use some. The most helpful review I've gotten lately was "Good grammar but a little OOC." I've gone over the fic and was unable to spot the OOCness, and the reviewer was anonymous, preventing me from contacting them. :(
