Personally I think the 2 can coexist.
In our dojo I stick to the Shodokan grading syllabus so folks can get in some serious practice as regards refining technique and understanding the nature of their dynamics in kata. Then we have randori practice where the kata techniques are to be applied in a more fluid environment where things move faster with more unknowns and dynamism.
To me, technique should not suffer when applied in a fluid/dynamic manner - in fact this is one of the things I use as a benchmark to judge my students' development -how well they can apply things effectively, acurately and fluidly while under pressure.
Something I noted in particular when I hit Shodan a while back was the progressive increase in accuracy that techniques should have as one progressed, and this technical accuracy should prevade all elements of training, especially during exercises that help train fluidity, timing etc.
Generally, for about 2 weeks after a grading has taken place in our dojo we tend to move away from the syllabus a bit and work on applying things fluidly and under pressure - plenty randori in other words. The idea here is to hone and adapt the "static" form to fluid situations without losing technical (and practical) effectiveness.
Difficult sometimes - yes, but far from impossible, and it serves us well as we progress in our gradings beyond Shodan as well.
Just my 2 cents.
