The biggest problems with Diana are:

Her Q has an insanely long cooldown

That shield is good, but it I think it too much damage

Her Ult has a really low cooldown, even if you use it on opponents not afflicted with moonlight, it'll still be available when you need it

I was using Diana earlier, and I always end up with a 1v1 against a Renekton. The said renekton was able to burst my team down alone and is fairly good. But it the multiple times we battled, I always end up victorius. I tag him with Q, follow up with R activate W then E, our battles usually last a minute or So but even if he has a lot of items and very tanky too, I am still able to burst him down.
