Question about Talents in Skill

[player6294450 0]

Hi guys, I have been playing this game for couple of month now, and have a question about the talent in the skill. Not sure which talents gives you the most effective, powerful set up for the Battle Arena but I keep getting taken out by the other players with much less BR and level. I do have all my weapons in the set of 4/4. correct Gems/ Runes, didn't mix the PATK and MATK. 

other day, one of the player in my server mention that i need to adjust/activate certain talents in the skill to be more effective in the Battle Arena, but didn't specify which ones I need to activate, upgrade to get better outcome of the Battle Arena..  Attached is the screen shot of my activated talents in the Skill.  can someone show me which ones I need to activate or upgrade? 

Thanks !!!
