I made a previous thread for general tips for Forge, here is some issues I run into with specific leaders. Semi comedy involved
VS Isabel - Have yet to lose to Isabel. Poor lass. She can never get map control then vultures/cyclops/forgehog ruins her day.
VS Johnson- Anyone actually play as this leader? This dude is AWOL.
VS Anders- Off having relations with Johnson? havent seen her.
VS Jerome- Tough match up, If you use Grizzly drop thats GG when three Spartans of Jerome jack your -Yoink-. Combat salvage doesnt replace your jacked vultures either. Grenade marines and Forge do pretty well against jackrabbit openings assuming your good about unit placement. This is one of the leaders i recommend going infantry against as Forge to better deal with his spartans. Shock round cyclops does very well against the mantis. Use your eco advantage to overwhelm early and often.
VS Cutter- You will think your doing well until ODSTs rain down on your face. Forge can match Cutters unit output but cant keep up with his speed and ability to pick engagements or counter capture nodes and destroy minibases. Transport counter attack has some high payout when executed correctly. Must split units well and have good defense to keep from being picked apart by his guerrilla play.
VS Kinsano- An easier version of Cutter. Split units well and use Forgehog to defend mini bases and power nodes from Kinsanos constant unit calldowns and multi-area harassment. Good defense and making use of Forges Economy will win this one. Vultures ruin her day as two of her damage dealing leader powers cant touch them nor can her leader, who i currently consider to be a complete waste of resources.
VS Shipmaster- Shipmaster struggles against forge in direct engagements like he does many other leaders. Get early game advantage with Forges eco to take a fast expo and powernodes. get up good defenses in preparation of a transport behind your base. Always leave some of your army back home vs shipmaster unless he just used teleport and always have detection units, Vultures/wolverine or vulture nightingale depending on his army comp. Mass infantry is a great way to get suicide grunts teleported onto your army and is not recommended to move a massive infantry ball around against this leader.
VS Atriox - Grenade marines and forgehog can match Chosen and grunts. Dont give up map control. Combat salvage and heavy metal. Fully Upgrade Heavy metal to combat eradication and make sure you use Heavy Metal when you are being eradicated or your army is toast.
VS Colony- Hunters Brand Hunters Brand Hunters Brand. Damn that spell is annoying. Never clump up your army vs colony. hunters brand will vaporize 40 population of infantry early on. There isnt much time to put heavy metal in place either as the spell hits fast unless he uses it when you already have heavy metal up…which is dumb. Vultures, counter units, and combat salvage.
VS Decimus - Not much experience with this one. Dont clump units because vortex, i actually recommend getting scatterbomb as Decimus cant micro his army away if hes using vortex and the animation takes awhile. Scatterbomb sucks but staying in the blast field during the entire attack is still devastating. Watch for heavy rushes from this one.
VS Arbiter - Mostly just see enforcer rush, jackrabbits/forgehog i guess? Never have too much trouble with this one.
