UoL vs H2K EULCS Summer Split Pick and Ban

I am relatively new into analyzing League Games, but in autumn, I will start coaching teams in my highschool. I started a few weeks ago analyzing LCS Games, watching Leaguecraft 101 etc. to improve my ability on 5v5 League Strategy. This is my try to analyse the Pick and Ban UoL vs H2k:

1. Ban phase
    Blue Rumble - good Matchup against Shen, high prioritized later, Good in Meta, Nice Teamfight
    Red Zac - Broken in this Patch, good Lane Pressure and Teamfighting
    Blue Lucian - Midlane/ADC Ban, good earlygame, prevents hypercarries from spiking
    Red LeBlanc - Good Matchup against Controlmages and other Lategame stuff, can assassinate immobile hypercarries really fast.
    Blue Galio - Good Wombocombo, Anti-AP, Insane Tank in Teamfight and nearly even with Shen in Teamfight
    Red Rakan - Good to catch immobile carries, decent lane with sustain + Xayah worse without him, good against protect the adc comps
1. Pick phase
    Blue Shen - high prioritized with Rumble Ban, global pressure after six + insane tankyness. Decent in Lane
    Red Thresh - good all around support, pressure with Hook and safety with Lantern, good engage when landing hook
    Red Syndra - Febiven Comfort Pick, S-Tier in Meta, Scales well, Lucian out, decent blindpick
    Blue Twitch - immobile hypercarry will work after rakan, leblanc, zac out,  Shen R can protect him, Lucian out 
    Blue Vladimir - very good matchup against Syndra with Pool, scales well and good teamfight. Safe against Jungler with W
    Red Kennen - after not mirroring, Top or Bottom will get outbanned -> flexpick Top/Bot Good Lvl6 against Twitch with all-in with thresh, also win Top because of outranging shen
2. Ban phase
    Red Braum - good disengage against Thresh with Twitch/ compensate bad matchup
    Blue Elise - S-Tier earlygame jungler, deny jungler pressure on their hypercarries
    Red Warwick - good against graves, lee and ivern, open junglers
    Blue Lee Sin - with earlygame and lategame insecs good against twitch, last earlygame jungler out
2. Pick phase
    Red Ivern - The support to the double tanks + carries, good midgame, no counters left open
    Blue Rengar - wins jungle matchup, good snowball potential
    Blue Blitzcrank - very aggresive, but hook or nothing, giving up botlane lane pressure until jungler gank + hook completely, Kennen could be afraid of the matchup
    Red Varus - Kennen Toplane, safe poke adc against Blitz, winning lane with weak Twitch + Blitz

Please go through my thoughts and complete/correct it, so I can improve my analyzing skills. Thank you. I am sorry for my bad english, I am not native :)
