This is true, but the whole point of weather is to 'make up' for the slot of the inducer AS WELL AS give even more advantages to the team. The advantages Rain can bring for a team should often outweigh the losses used to fit in an inducer with good synergy- and it often DOES make up for it- which is why weather is so popular. If the slot lost for weather brought more bad to teams than good from the weather boost, I'm sure weather would be used a whole lot less.Non weather teams aren't reliant on weather like weather teams are, which in itself is another team slot since weather teams must run a perma-inducer on their team.
If you put in numbers, which usually only work on paper yet still provide an accurate view of advantages of weather teams, it mught look something like this:
Total Amount of weather boosts x power of boost - 1 (Inducer) = Net advantage of using that weather. (in pokemon)
Let's plug in some numbers. Say, there's a standard Poli / Rachi / Torn-T / Keldeo / Latios / Rotom-W Rain team. (I'm using Rain since it's largely regarded as the best field effect) The amount of offensive boosts would be, not counting inducers since they are the 'negative':
Keldeo's HPump
Tornadus's Hurricane
Latios's Surf
Rotom's HPump
Now, times power of boosts:
1 HPump x 1.5 Water boost
1 Hurricane x 10/7 Accuracy boost
1 Surf x 1.5 Water boost
1 Hpump x 1.5 Water boost
Add it all up and we get 3 x 1.5 + 1 x 10/7 = approx 6.
Now, -1 for Politoed = 6-1= 5.
So, if all that was used throughtout the match was Rain boosted moves, facing a team with Rain would be like facing the team with FIVE WHOLE MORE POKEMON than if they didn't use Rain, because pf the boosts Rain gave. Getting hit by 2 Keldeo's HPumps in Rain would equal getting hit by 3 Keldeo HPumps out of Rain. 2 Latios Surfs in Rain = 3 out of it. The Rain effectively almost doubles the amount of offensive 'pokemon' you face.
Now, I recognize that this method isn't the most accurate way to display weather advantages- as ther are many other factors involved that have not been accounted for. However, it does show one thing- that the boost weather gives often far outweighs the disadvantages of using weather inducers, as long as the team uses the weather efficiently to some point.
For demonstrative purposes, I'll do a Hail calculation with Aboma / Kyu / Tenta / Reun / Conk / Heatran
moves boosted by Hail:
Kyu's Blizzard
Boost:
1 Blizzard x 10/7 Accuracy boost = 10/7 -1 to account for Abomasnow: 3/7. This number is a lot less than the amount for Rain- but it's sti higher than 0 / negative. Hail brings advantages, but often not nearly as much as Rain.
