Are plants at a disadvantage against zombies?

I think they only do that because many of them want to place a barricade down and just use their drone the entire match, what they don't realize is they're blocking other players when they spawn and really they're not helping much in the long run.

Personally I find a lot of potted plants to be useful but many more are worthless. The only ones I use regularly are the ice peashooters because I play an Ice pea and their freeze effects stack with my own, Doom Shooms when I play a cacuts because I place iron maidens around them to protect them from summoned zombies and players as they recharge, heal flowers because I'm always on the move and being able to plop down a healing flower is of great use to me, goop shooms because they slow people down and that's just fun and bamboo shoots. I love having 4-5 of them downpouring on my foes. >:D

Zombies definitely have an advantage in the hitpoint category.. the football players have 200 hps.. highest plant has 150'ish?  and that's the chomper which is screwed the moment it eats something

The chomper is only screwed if he's running out into a field of zombies. Playing each class correctly keeps you alive.

Also, the base health stats for each team are actually the same except for the All-star who only has a 25 hp advantage over the Chomper who has 175 and that hardly makes the entire zombie team have an unfair health advantage. There are of course exceptions with some variants but thing actually are balanced.

I agree with alot of the above responses and used to think the same thing till I really started playing all the classes in the game more. One has to remember it "seems" as if the zombies are over powered because:

-like in games like WOW advanced players and/or older players tend to play the bad guys (not all just an observation)

-plants are forced into a position where they are more clumped and zombies can spread 360 deg and present less of a target (huge!)

-you only need a swarm mentality at times to take a garden as a zombie so it IS easier

-Plants actually have to be conscience of their spacing as not to get clumped for imp punts or other AOE dmg and most plant groups have PATHETIC healing going on.  On most runs I will see heal boasts going to flowers with only 10-30 heal points during an entire session!  And they wonder why they cant hold a garden.  I average 30-60 heal points when I play flower and sometimes as high as 150 heal points.  A well held garden will see 1-3 sunflowers activly healing and rezing players.  This last point is 50-70% of why plants cant hold gardens IMO.

Plants are, as always, a defensive plant. (pvzgw2 doesn't count yet) They are there to stay in one place while zombies throw themselves (in a matter of term) at them. In pvzgw, they are build as defense, mainly due to stationary items like flower pots and Gatlings. (pea gating + solar beam) The game is peashooters, sunflowers and chompers defending while cactus picks off the zombies from the top. The zombies however, are made to be in a pack, surrounding them, with foot soldiers, rocketing in with smoke bombs and zpgs to pick off anyone in the middle. They both have strengths and weaknesses. Zombies are bad by themselves and plants can't survive long without a base around it. You just need to lean and ajust.  

These days I also see a lot of plants, like peashooters, instead of holding the garden together with sunflowers and chompers, are sniping. SNIPING!!!! So the only things holding those gardens together is low healthed sunflowers and chompers useless once they get 1 kill. Sure, sunflowers heal, but think. Every 0.5 seconds, a gatling gun bullet is shot. With sunflowers puny 100 health, It will only take 12.5 seconds to kill IF THERE BY THEMSELVES. And it's a gatling gun, so what about things like the concrete laucher?

What kind of idiot would sit in a garden with a peashooter? The only plant that would need to sit in the garden is the Chomper... in fact nobody should be sitting in the garden until zombies get there. Peashooters and Cactus are most effective at longer ranges. They should be sniping zombies before they get into the garden. Peashooters should have an eye on the garden at all times so they can utilize their splash damage or launch a bomb. The only time I'd be in the garden as a peashooter is to cancel out capturing by any zombies.
