NO! Absolutely NOT.
Chompers already have so much going for them.
Instant snare spikeweed.
Easy goop to burrow/spikeweed combo.
Getting a spikeweed back after swallowing an enemy.
And then there is variant specific advantages.
Breath Chompers speak for themselves.
Hot Rod Chomper's insane speed.
Chompula's ability to heal on swallow.
Armor Chomper's massive amount of health and damage.
Yeti Chomper's endless supply of icicles.
Disco Chomper's (for those of us who have it) powerful legendary mode.
Unicorn Chomper (for those of us who have it) with the special warp ability.
Combine these specific advantages with Chomper's already over the top abilities, you WILL find most of them are hard to counter in MOST situations, mainly Hot Rod, Fire, Yeti, and Unicorn.
Also, remind me of a time in this game where you played as a Chomper and saw several players using your counter, the Engineer. I can't.
Engineer is meant to be your main counter, but you really don't have much to worry about, as you hardly see people play them anyway.
This leaves the other counter, Pirates. Being the Zombie team's sniper class, it's just to be expected they would have an advantage over you, a melee class. They should be able to pick you off from a safe distance.
But even then, they shouldn't be focusing on a Chomper in a competitive game. They should be aiming for the healing Sunflowers, and those oh-so-powerful Citrons, to help out their team.
You could argue Soldiers and Super Heroes have advantages over Chomper as well, but I have a counter to that.
Soldiers can pose a threat to you, being a powerful character at mid-close range, along with their ability to Rocket Jump/Leap away from you.
How to counter: Burrow towards them to bait their jump. If they do, simply get out of the ground and goop them. They should be helpless from there, open to a spikeweed. If they're at a long range, just try to stay out of their way.
Super Heroes DO pack more of a punch (literally) at close range, and have a ranged laser as well.
How to counter: If they get close to you and start trying to punch you, place a spikeweed while running backwards. If they are trying to attack from a range, burrow towards them. From there, just get up, and goop, spikeweed, and they're vanquished. If they're trying to snipe (which they shouldn't be doing) just stay away.
If you do see an Engineer, just know that he is your counter and try to stay away. If you see he is busy with other Plants or on his Blaster, just burrow towards him and place a spikeweed at his feet. Don't give your position away to these guys with goop if they're on the blaster, they will just turn and shoot at you. If you know he has already used his Stun Grenade, you can move in on him if you feel like you can take him.
Other then that, congratulations! You now know how to beat your main counters.
