Okey. First you buff his shield skill. And this turn him in broken character. Shield is too strong and don’t have any timers. This is ridiculous. Endless 1 million shield.
Now you add for him second turret. With endless broken shield from first skill and shield system wheh full health turret give to Castellian extra shields he became almost unbeatable. Especially when your team have many energy heroes.
How about add timer to shield from first skill? How about remove rockets and extra shields for Castellian if player decide put second turret? This will be fair and pretty balance. Or you have one turret anf few nice extra bonus or you have two turret with more damage but without extra bonus.
