Possible buffs to Shyvana that could make her more viable

PASSIVE: INNATE: Shyvana deals 10% bonus physical and magic damage to Dragons and to Vilemaw. (stays the same) Shyvana gains 10 / 15 / 20 / 25 bonus armor and magic resist (at levels 1/7/12/17) and 10 / 15 / 20 / 25% Slow Resist for 2 seconds upon damaging an enemy with an ability or a basic attack (stacks up to 3 times for a 6 seconds maximum duration, afterwards refreshing with further damage applications)

Note : this is Sejuani's old passive (pre-rework) and i think it's ALOT more reliable than Shyvana's passive ,and She would get the stat bonuses REGARDLESS of how many dragons your team has killed. Shyvana's current passive is way too risky and i believe this newer one encourages skirmishes alot more and goes more with her theme as a tenacious dragon and as a diver (also maybe changing slow resist to tenacity but that might be overkill)

TWIN BITE: COOLDOWN: lowered to 8//7/6/5/4 from 9/8/7/6/5 Shyvana Base AD: changed from 66 – 123.8 to 69 - 126.8

BURNOUT: now damage ticks every .5 seconds instead of once every second, damage stays the same. (I think this is a nice QoL buff similar to what was done with Singed, sometimes damage from W takes too long to register)

Note : Twin Bite's Scaling was nerfed significantlly in patch 8.4 which was frustrating , i think lowering the CD of twin bite by 1 or 1.5 seconds(s) and raising her base AD can bring a bit of build diversity with Triforce since her bonus AD scaling isnt so great and this should help with proccing the Sheen passive reliably which is probably Shyvana's biggest problem with Triforce

Opinions??
