thankyou for your details i will work on it :)

I would call this a good guide. It contains good information about items, masteries etc. and has a good coding but you could add lots of other things. I am really missing information about warding what is very important as a support. Also you could discuss some match-ups, what carries synergize with leona, how do you counter other supports and just some simple information about your gameplay.
Overall a good guide that deserves my +1 vote but still improvable.
