Very limited payload
Very limited weapon selection
Very high maintenance to flight hours ratio
The Tiger's development was a clusterfuck and a lot of it carried over to its actual service life because it was made by anally retentive Europeans more interested in sabotaging eachothers' industries than making a good product. They never settled on a standard cannon for it so the French and Spanish ended up with one gun and the Germans who wanted to use a Rheinmetal gun ended up having no gun at all. Neither model can even fot more than 300 rounds which makes it worse than literally any other helicopter at basic CAS tasks.
Tigers also have no compatibility with commonly available American weapons like the Hellfire and Hydra and use mediocre French rockets and missiles which are not available in numbers if made at all nowadays. Even if they did, it wouldn't help them much because they have garbage take off weight and maximum ceilingm can't carry a significant combat load and can't do attack and interdiction either as a result, or go into places where an Attack Helocpter is most useful ie mountains.
The Australians bought them and are still dealing with the buyers' remorse. Just a shitfest of a program. What's even more egregious is that Italy was making it's own helicopter and put into service more than 10 years before and it is actually really good, the Mangusta, and unlike the Tiger which is a dead end, it had export versions and also a successor.
