You my thoughts Thermo, theme for the win.
Yes anyone can exploit combos or rules to gain in game advantages.
In spite of that, tournament winners are ultimately determined by skill (both in list building and in using that army on the field).
You have done so well with Rohan in spite of what common opinion of them stated, the fact that you are a relatively new player supports my belief that anyone who practices with a list they love can hone it and make it compete.
Stick to pure fluffy Rohan, without it you'll start losing the hearts and minds of others
